Step 1: In a skillet over medium heat, heat the olive oil. Add onions, salt, nutmeg and pepper. Cook, stirring occasionally until browned and tender (20-30 minutes).
Step 2: Spread about 1/4 cup of the onion of each of 2 slices of bread; cover with cheese and top with remaining bread slices. Spread butter on top of bread.
Step 3: Heat a skillet over low heat (I would use the same skillet as I cooked the onions in) and place sandwiches, buttered side down in the skillet. Grill sandwiches for 5-10 minutes per side; cover pan during last few minutes of cooking to melt the cheese.
