1 large apple, cored and thinly sliced
In a small saucepan toss together the apple, cinnamon and sugar. Cook over medium-low heat for about 5 minutes, or until the apples are just beginning to soften. Remove from heat and set aside.
If using a demi-loaf of bread, slice into ¼” slices. If using full slices of bread, cut into quarters. Grill or toast the slices until they start they start to darken around the edges.
Using a vegetable peeler, slice away thin strips of the cheddar cheese. Build the crostini by layering the apples and cheese on the bread, in whatever proportions fit your taste. I prefer to go heavy on the cheese, but I won’t judge if you prefer more of the apple flavor.
