Yes you can make a Grilled Sandwich without butter. Really you can!

The bread is more fattening than the butter. Say that you put a patty of butter on your sandwich, that’s 36 calories. Two slices of bread is 134. Cut off the skin of the bread and you’re back down to 64 calories for the two slices, and then you can add on your butter for the same overall calories as no butter with skin.
