Healthy mexican cooking tips?

[mandizzle]

I love mexican food, but I cant seem to think of healthier versions. I'm trying to watch my calorie intake so if you know of any ideas or recipes around 500 calories or less thatd be awesome! Thanks!
I forgot to add that I am vegetarian

Do not use lard in your refried beans - use olive oil instead
