oh man, i love mexican food! i think a few smart places to start would be, chicken or lean meats, go for a lighter fat cheese, go heavy on tomatoes, tomatillos, onions, peppers, etc - more veggies the better!!! and i have found these great tasting whole wheat tortillas that make it better for me too - i love a good chicken quesidilla on cold days, lol and these slight adjustments will make a HUGE impact for staying on track! also, i love avacado and i do believe its high in fat, but it falls under the 'good fats' so i indulge, lightly, with the avacados, lol. hope that helps! =D
Blessings!
