Még ha kevés hozzávaló van is, összedobunk egy főételt.

It means even if.

So:

• ha = if
• még ha ... is = even if

This is a common Hungarian way to introduce a concessive clause: a clause that says something does not stop the main action.

So in this sentence:

• Még ha kevés hozzávaló van is = Even if there are few ingredients
• összedobunk egy főételt = we’ll throw together a main dish

The is here is part of the pattern, not the ordinary also/too meaning.

No, here is does not mean also or too.

In még ha ... is, the is is part of the fixed concessive structure:

• Még ha esik is = Even if it rains
• Még ha nincs is időnk = Even if we don’t have time

So in your sentence:

• kevés hozzávaló van is is not a random combination
• it is the clause kevés hozzávaló van wrapped into the még ha ... is pattern

A good learner shortcut is:

• még ha at the start
• is near the end of that subordinate clause

Because after quantity words like kevés, Hungarian normally uses the noun in the singular.

So Hungarian says:

• kevés hozzávaló = literally few ingredient
• but in natural English: few ingredients

This is very common in Hungarian:

• két könyv = two books
• sok ember = many people
• kevés pénz = little money
• kevés hozzávaló = few ingredients

So even though English uses a plural noun, Hungarian usually does not after numbers and quantity expressions.

In Hungarian, when the subject is a quantity expression like kevés hozzávaló, the verb is usually singular in this kind of existential sentence.

So Hungarian says:

• Kevés hozzávaló van.
• literally: Few ingredient is.
• natural English: There are few ingredients.

This is normal Hungarian grammar. The whole phrase kevés hozzávaló behaves as a singular quantity expression.

Compare:

• A hozzávalók ott vannak. = The ingredients are there.
  Here hozzávalók is explicitly plural, so the verb is plural.

But with kevés hozzávaló, singular van is the expected form.

Hozzávaló means ingredient, especially in cooking.

It is the usual word for something you need to make a dish.

So:

• hozzávaló = ingredient
• hozzávalók = ingredients

In context, kevés hozzávaló means there are not many ingredients available.

A related word you may also see is alapanyag, which is more like raw material or ingredient/base ingredient, but hozzávaló is very natural in recipe and cooking contexts.

Összedobunk is a fairly colloquial verb here. It means something like:

• we’ll throw together
• we’ll quickly put together
• we’ll whip up

It suggests making something quickly, without too much fuss, often from whatever is available.

Parts:

• össze- = together
• dob = throw
• -unk = we

So literally it is something like we throw together.

In cooking, this does not mean literally throwing food. It means making something fast and casually.

Because Hungarian verbs show the subject in the ending.

Here:

• -unk = we

So összedobunk means we throw together / we will throw together.

That is why Hungarian often leaves out the subject pronoun:

• összedobunk egy főételt = we’ll throw together a main dish

You could add mi (we) for emphasis, but it is not necessary:

• Mi összedobunk egy főételt.

That sounds more emphatic, like we will do it.

Because in a neutral declarative sentence, the verbal prefix usually stays attached to the verb.

So the neutral form is:

• összedobunk

Hungarian prefixes often move after the verb when something is strongly focused, negated, or questioned.

For example:

• Összedobunk egy főételt. = neutral
• Egy főételt dobunk össze. = the object is more focused
• Nem dobunk össze főételt. = negation

So in your sentence, összedobunk is the normal neutral order.

The -t is the accusative ending, which marks the direct object.

So:

• főétel = main course / main dish
• főételt = a main course / main dish as the object of the verb

Since összedobunk is doing something to that noun, Hungarian marks it with -t.

And:

• egy = a / one

So:

• egy főételt = a main dish

Yes, it could.

• összedobunk egy főételt
• összedobunk főételt

Both are possible, but they feel slightly different.

With egy, it sounds more like:

• we’ll throw together a main dish
• one dish, a specific instance of a dish

Without egy, it can sound a bit more general or less explicitly countable, depending on context.

In this sentence, egy főételt is very natural because it clearly presents one main dish as the result.

Because Hungarian very often uses the present tense to talk about the future when the meaning is clear from context.

So:

• összedobunk egy főételt

can mean:

• we throw together a main dish
• or, more naturally here, we’ll throw together a main dish

Hungarian does have other ways to express future, such as:

• össze fogunk dobni

But in everyday language, the simple present is very common for future meaning, especially when the sentence sounds like a plan, decision, or obvious next step.

Because Hungarian often puts the condition or concession first, especially when it sets up the main point.

So this order:

• Még ha kevés hozzávaló van is, összedobunk egy főételt.

feels natural because it first gives the obstacle:

• Even if there are few ingredients...

and then the main message:

• ...we’ll still make a main dish.

This is similar to English, where Even if... clauses also often come first.

The opposite order is also possible in principle, but the original order is the most natural and straightforward here.

The emphasis is on the contrast:

• there are only a few ingredients
• but that does not stop us from making a main dish

That contrast is created mainly by the concessive structure:

• Még ha ... is

And the choice of összedobunk adds a practical, confident tone:
even with limited ingredients, we can still quickly make something work.
