I just make a stir-fry for dinner with whatever vegees I want, like green peppers, green onions, zuchini. Then I add chili powder and cumin to make it "Mexican." Top with salsa on a big bed of lettuce. The salsa kind of acts like the salad dressing, but you could also use a little WF Italian with some vinegar added. You won't have the cheese or sour cream, but remember...it's only temporary....
I really missed my guacamole and my coach said I could substitute my olive oil for 1/4 of an avocado, every now and then. It only made 1-2tbsp of guaca, but it was better than nothing.
