Namazdan sonra yemek seni sunulacağım.

After Namaz I will serve you food.

Thank you

I´m not positive but I think it´s this:

Namaz´dan sonra yemek seni sunacağım.

I think seni sunulacağım is I will serve myself to you.

It should be: Namazdan sonra sana yemek hazırlayacağım.

You should keep in mind that accusative (-i,ı,u,ü indicates  the direct object.

It should be with dative (-a ,e) => sana sunulacağım ( I will be served to you)  

This sentence is passive with unclear agent. (who will serve me to you is unclear)

If "ben" (I) is the subject and the sentence active, "kendim" (myself) will be the direct object => kendimi (what will be served is "myself", and who will serve it to you is "me")

sana kendimi sunacağım => I will serve (sunacağım) myself (kendimi) to you (sana).

I think something still wrong with it. In this sentence, "offer" seems to me a more proper English equivalent for "sunmak" than "serve."
