Butter every side of every piece of toast and then use American Cheese (preferable two to three slices) as your filling. Occasionally I'll use a pepperjack mix with American but I like to keep it simple. Then I would put some tinfoil over it and pop it in the over at 350 until it looks cooked. Just check up on it until it looks good that or you can drop that baby on a pan and cook it on 4-5 or whatever medium is.
