Use low carb flour shells, morningrstar farms veggie burger crumbles, and if you crave sour cream try walden farms zero calorie, zero carb blue cheese salad dressing. If you insist on cheese, there are several brands of lower calorie, zero cholesterol soy cheeses. I forget who makes it, but there's a soy Mexican sausage, 'Soyrizo", if you like that in your taco. If you like burgers instead, Boca Burgers (also veggie) are 70 calories, with a whole wheat, low carb bun, that's a 150 calorie burger before condiments.Diabetics don't have to eat like they're being punished nowadays. I've lost 43 pounds in 12 weeks using the veggie burger products and lots of salmon.
