Maybe you can just pick better restaurants, or just make better choices at bad ones.
If I had to go to Taco Bell, I would get a burrito supreme or whatever they call it or if they have fajitas, that, and unwrap it from the tortilla. I'd probably have to order several of them in order to get enough food.
At a pizza place I'd see if they have wings.
At a burger place I'd get a burger, maybe a double bacon cheese burger and eat without the bun. They used to sell baked potatoes at Carls Jr but I don't know if they still do.
If possible I'd see if we could trade up a bit. Like maybe find a mom-and-pop Mexican taqueria instead of Taco Bell, especially one where they have sessos and lengua on the menu and you have to know a little Spanish to know what to order. The spicy carrots and jalapenos are good, the hot grilled chilles, all the delicious salsas. Any kind of taco can be eaten with a fork and no tortilla (or just eat only a couple of the tortillas) and they sometimes have a meat stew, I think it's called birria, and sometimes menudo on Sunday mornings.
