It's OK, but it could be improved- there are too many paragraphs in my opinion, so try to merge some. Also, though they're correct in terms of grammar, the sentences are all short and similar. You could improve the quality of the writing if you joined some of them up, which would stop the I-did-this-then-I-did-that style:
We ate the food cooked by my mother. I enjoyed the food cooked by her.
I see no need for the second sentence and the repetition of who made the food- you could do something like this:
My mother (had) cooked the food, and I enjoyed it a lot.
