Questions & Answers about Моя подруга делает котлеты из куриного фарша и ест их с салатом.
Because моя has to agree with подруга.
- подруга is a feminine singular noun
- so my must also be in the feminine singular nominative form: моя
Compare:
- мой друг = my male friend
- моя подруга = my female friend
So this is just normal adjective/pronoun agreement in Russian.
Usually, подруга means female friend.
In some contexts, it can sound like girlfriend, but that is not usually the default meaning. If someone clearly wants to mean a romantic partner, Russian often uses девушка instead.
So in a sentence like this, most learners should understand моя подруга as my female friend unless context suggests otherwise.
