Now that's a pizza. I doubt schools serve that.
Hot dogs are mostly protein, particularly the ones made out of chicken or turkey. Super hamburgers do have a risk ~ the bun ~ too much carbohydrate.
Same with french fries. Entirely too many carbs in there if they've been cooked twice ~ and all the fiber is broken down. Do them at the right temperature and you'll have nearly as much oil at the end as you started with, plus you can use special blends that provide Omega 3. , hot dogs, super hamburgers, french fries,
I suspect the fat is in the cheese. Not all pizza has meat. Bread has some fat, but Mozzarella is 25% fat by weight. And, BTW, pizza without cheese is "tomato bread" (which is not bad, just not pizza).
LOL, are you saying the food they serve is good for our students? ;)
