It sounds like a bit from a 90's stand-up comedy routine: "Why do they call it grilled cheese when everyone cooks them in a pan?"
1. Ham, Cheese & Apple
Whole Grain Mustard
2. Tomatoes, Mushrooms & Onions

Preheat a grill with GrillGrates to medium low or about 425°F at the surface of the grates. If you would like, turn a couple of your GrillGrates over to the flat, back side in order to griddle your sandwich.
For each sandwich you will need two slices of bread and softened butter.
Assemble the sandwich by spreading a thin layer of softened butter on one side of each of the slices of bread.
Flip the bread over. If the sandwich has a spread, such as pesto, spread it on the un-buttered side.
Cover the entire surface of the bread with cheese and then add whatever other ingredients you want.
Put the sandwich together and take it to the grill.
Place the sandwich on the rails of the GrillGrates or on the flat back side of the GrillGrates and close the lid of the grill.
After 2-3 minutes check the underside of the sandwich to see what kind of color you have. Ultimately you are looking for a nice, dark, golden brown.
If you're cooking on the rails, lift and twist the sandwich 90 degrees. If you are using the flat back side go ahead and flip the sandwich. Close the lid.
Repeat this process until you have achieved the desired color and "oozeyness" (it's a technical kitchen term) of your cheese.
