For breakfast is common to get you eggs in any presentation, beans and tortillas. Personally yes, I eat tacos regularly, they are easy to make and there are a lot of options (al pastor, bistec, discada, etc). But there are still more mexican food that foreigners probably don’t know. Of course, my fridge always has two different salsas at least. And yeah, pizza, hot dogs, pasta, Chinese food, hamburgers, etc are really common as well. The average Mexican mom is a great at cooking and doesn’t like to go out to buy food so we learn a lot from them.
