While I have been served grilled cheese sandwiches with mayo on the outside my preference is to use neither mayo nor margarine or butter. I just give the pan a light spraying with cooking oil. That's all heavy wheat bread and good cheddar cheese need.
I can not eat all the calories I want. Butter and mayo are nearly completely gone from my diet.
