You'll need that Foreman Grill I'm always mentioning. If you don't have one get down to your local thrift shop and buy one for around $5. There is always a good amount of these on the shelves. I personally use this grill consistently for making these types of quick dinner fixes.
1 small ham sliced thinly
Processed cheese slices
Butter or margarine
Take out one of those loaves of bread you've been meaning to use up and slice it horizontally after it defrosts. If it has a good amount of bread in the middle, you can rip out a bit so that the sandwich fits easily in the Foreman Grill.
Add a few slices of ham in the middle and a slice of processed cheese. Add a bit of mayo on the inside if you enjoy that on your sandwiches. Butter the outside of both slices of bread and place in your Foreman Grill and close. I sometimes weight it with a pot to hold it down a few minutes and make the sandwich compressed.
Try a bit of tomato or onion in the middle too!
