Taco Bell has a ton of low fat items, if you order them right. The bean burrito has 9 grams of fat with cheese, so if you dont get cheese im sure itd be like 7 grams.
You can get a lot of their foods under 8 grams of fat if you:
Always go for chicken as the meat.
Order the food as Fresco Style. Fresco style means no cheese, and no sauce. They put tomatoes and onions on instead. Then you can put your own mild sauce and tuff.

Taco bell is actually really healthy, if you get chicken. I dont know about the ground beef.
