At Wendy's, order a small chili, a baked potato, and a side salad. Slice open the potato and pour in the chili..Eat the salad separately. Order water or a diet beverage.
At Subway, go for a salad with meat, same drink deal.
Taco Bell has power bowls that are healthy, low fat, and tasty. I like the beef. I don't do Mcdonald's because I seldom find anything healthy on their menu.
Notice that there is nothing deep-fried on my menu suggestions. Give it a try.
