My sister made me one of these a couple of months ago and she told me I had to at least "try" it....and it was so so so yummy!
Sourdough bread (I didn't have any so I used my 9 grain bread)
1 slice of Pepper jack Cheese
1 slice of Mozzarella Cheese
1/4 Gala apple
Desired amount of onion.
Slice apple and onion saute them in a pan until soft. While those are cooking butter your bread. Assemble just as you would a grill cheese sandwich, add cheese onions and sliced apple. Cook until sides are just browned and cheese is melted. Let me know what you think if you try it!
