Preheat oven to 350 degrees.
Place sliced apples in a (well buttered) pie tin.
Sprinkle with a handful of unrefined sugar or any UnDiet-approved sweetener and (cinnamon, apple pie spice, pumpkin pie spice …).
Bake for 20-30 minutes until apples are soft. Roughly mash with a potato masher or fork right in the pie tin.
Scoop out the middle of one or more whole wheat bagels. Toast and butter. Or use thick slices of whole grain bread, or English muffins. You could also use whole wheat pitas or whole wheat tortillas. Heat and butter the inside of the pitas before stuffing with the cooked apples. Heat and butter the tortilla before rolling up around the cooked apples.
Pile the apple mixture on top of your bread of choice.
