4 very ripe plantains
Nonstick cooking spray
Preheat oven to 450 degrees F.
Coat a nonstick cookie sheet with cooking spray. Cut the ends off of the plantains and peel. Cut each plantain on the diagonal into 1/2 inch slices.
Arrange in single layer, sprinkle with cinnamon, and coat tops with cooking spray. Bake, turning occasionally, for 10-15 minutes, until plantains are golden brown and very tender.
