Heat a nonstick griddle pan over medium high heat. Wipe grill with butter nestled in paper towel. Add 4 slices bread. Cover bread with thin slices of cheese. Cover pumpernickel and Havarti grilled cheese with sliced tomato and chives. Cover cheddar and whole wheat grilled cheese with 2 slices of ham per sandwich and some sliced apple. Cover the crusty white bread-and-Gruyere sandwiches with spinach leaves and thinly sliced artichokes seasoned with salt and pepper.
Make 2 sandwiches at a time and transfer to a warm plate in low oven. Cut sandwiches corner to corner and serve a platter of mixed grilled sandwiches with your homemade soup.
