Found this recipe last summer. It is wonderful.
One-Ingredient Ice Cream
"This recipe is dairy-free, nut-free and completely vegan, so almost everyone can enjoy it. All youíll need is one very ripe banana and a food processor or blender.
Peel the banana and chop it into slices about 1/2 inch wide. Place in a ziploc bag or container and stick it in the freezer for at least 1 hour (overnight works best).
Once itís frozen, remove the banana from the freezer and drop the pieces into a blender or food processor. Puree until smooth.
Enjoy! Frozen bananas have a natural creaminess that gives this snack or dessert a surprising richness."
