I saw a recipe yesterday that I just had to try. You can find the original here on 1840 Farm's blog: Grilled Cheese for Everyone. So, here is my quick version!
1 apple, center-sliced in 1/4-inch pieces (I used an organic Daisy Girl)
raw cheddar cheese, sliced thinly
Let cool slightly. This will be a bit messy. But, oh so yummy. Enjoy!
