The raspberries and Nutella are the stars in this sandwich, so feel free to swap out the Muenster cheese with a different mild variety. This is a sandwich you will fall in love with!
Place the bread slices on a flat work surface. Spread 1 tablespoon of butter evenly over one side of each slice of bread. Flip the buttered bread slices over and spread ¼ of the Nutella over each.
Warm a skillet over medium heat for 3 to 5 minutes. Layer each sandwich as follows: Slice of bread, butter side down, Nutella side up, ½ cup shredded Muenster cheese (or 2 slices), ½ of the raspberries, ½ cup shredded Muenster cheese (or 2 slices) and slice of bread, Nutella side down, butter side up.
Place sandwiches onto the hot skillet. Cook on each side for about 3 to 4 minutes, or until the bottom layer of cheese begins to melt around the edges. Cut in half and serve!
