I think the idea of some low calorie TB options is a good idea but "Drive Thru Diet", .....I just can't see it.
TB is actually one of my favorite pick-up places. I go once or twice a month. Like kaplods, I use it to make a Taco salad. I pick up a bag of shredded lettuce at the grocery store and break up a crunchy taco to add to it. The regular crunchy taco is 170 calories so I can have a large salad with a few calories. Sometimes I get 2 tacos and make a really huge salad.



But seriously, you can do a burrito-less burrito, meaning it's in a bowl. I love it with just lettuce, rice, chicken, cheese, and salsa. If I eat just half of it I can have it for around 250 calories. You have to play with it, but it can be a healthy meal. It's when you add the guacamole, sour cream, cheese, beans, etc. and wrap it in a 300 calorie largest-I've-ever-seen tortilla that it becomes a problem.
