Questions & Answers about Rellenaremos la empanada como tú decidas.
Why is decidas in the subjunctive instead of the indicative decides?
The word como introduces a method or manner. Because we are talking about a future, undetermined decision, we do not yet know how you will decide, so we use the present subjunctive decidas. If we were talking about a known, established habit like "We always fill it the way you decide," we would use the indicative decides.
The English translation says "however", but doesn't como usually mean "like" or "as"?
Yes, como often translates to "like" or "as". However, when it is combined with a subjunctive verb to talk about an unknown or open-ended method, it translates better as "however" or "in whatever way". So como tú decidas essentially means "in whatever way you decide".
Could I say Vamos a rellenar instead of Rellenaremos?
Yes, you can use the informal future Vamos a rellenar instead. The simple future Rellenaremos is often used for promises or definitive plans, but both are perfectly natural here and mean the exact same thing.
Do we have to include the pronoun tú in this sentence?
No, you can drop tú and simply say como decidas, because the verb ending already tells us who is deciding. Including tú just adds a bit of friendly emphasis, making it sound like "however YOU decide".
