4 slices soft whole-wheat bread
2 tablespoons butter, softened
4 slices cheddar or Monterey jack cheese
Try adding a bit of smoked mozzarella or fontina cheese.
Try adding a slice of deli meat or thinly sliced tomato.
To clean your waffle iron, lay a damp paper towel in the hot waffle iron for a few seconds to steam the leftover grunge, and use a Q-tip to clean out the crevices.
