Buy fresh fruit of your choice. Peel (and pit) peaches or apples and cut into segments/pieces. Put in a baking pan alone, or pour some 100% fruit juice in the bottom of the pan. Bake at 400.
Combine any of the below in a bowl. The only required ingredients are starred:
Melted margarine* (I recommend vegan Earth Balance)
A little flour (or pancake mix, starch, whatever’s laying around to help it stick)
Brown sugar, maple syrup, or any sweetener
Crushed nuts (almonds, walnuts)
Ground flax seed (or any seed) or even a little protein powder
Mix together and put the crumble/crisp in a second pan in the oven to bake.
After about 20 minutes, take out fruit pan and crisp pan and, if hot enough/baked to your liking, serve with the crisp on top of the fruit!
