As we were on a budget and wanted to spend our money on clubs rather than eating out everyday I decided to cook in the apartment most days.
There are several supermarkets in San Antonio, our favourite being the Hipo Centro just along the street which has a great meat counter. I took with me some mexican seasoning and wheat flour tortillas and made chicken enchiladas. Buy the chicken from the fresh meat counter rather than the chiller cabinet as not only is it better quality, the nice man will cut it into escalopes if you want.
I also tried my hand at this seafood paella, which I was rather proud of!
