4 tablespoons butter
8 slices white Hawaiian sweet bread
8 slices sharp cheddar
4 slices provolone
8 pineapple rings (from canned pineapple, drained)
1/4 to 3/4 cups teriyaki sauce
Spread butter on one side of each slice of bread. In a large skillet over medium heat, place half the bread slices butter-side down. Top each slice of bread with 2 slices cheddar, 1 slice provolone, 2 pineapple rings, and some teriyaki sauce. Top with a second slice of bread, butter side up.
Cook until bottom bread slices are golden brown, 2 to 4 minutes. Flip and cook until golden brown and cheese is melted, 2 to 4 minutes more. Serve immediately.
