Drizzle Olive Oil (to taste) evenly over a baking sheet.
Peel and slice the Plantain (3) into rounds, add to the baking sheet and toss to coat in the oil.
Sprinkle with Chili Powder (to taste), salt, and pepper to taste. Bake for 20-25 minutes, flipping half way through. The outside will be crunchy while the inside slightly soft. Allow to cool.

Saute for 4-5 minutes or until the shrimp is pink and fully cooked.
