Slice of wheat bread = 90 calories
Slice of bologna = 90 calories
1 Tbsp Mayo = 90 calories
Slice of american cheese = 90 calories
So with two slices of bread to make a sandwich, with two slices of bologna and two slices of american cheese, i.e. the world’s most boring sandwich, that’s 90 * 7 = 630 calories. Some american cheese it even a bit more.
A Quarter Pounder with Cheese is 510 calories.
