I have a weakness for Mexican food, so I whipped this up last night.
Reconstitute 1 cup tvp (texture vegetable protein) granules with 1 cup boiling water and stir in taco seasoning packet.
I used some light corn chips (1 g fat/serving [I used 12 chips which is two servings]) topped with about 1/3 of the TVP and 1/4 cup shredded 2% mexican cheese and salsa (between 1/4 and 1/2 cup) and nooked it in the microwave for a minute. Then I added shredded lettuce and a couple tbsp of fat free plain yogurt (you could use f/f sour cream but this was all I had on hand and it worked great). Added up that cal and fat at the end, >450 cal and about 8 grams of fat for a HUGE meal.
