Set the oven to broil and position a rack in the center of the oven. Spread the plantain chips in a single layer on a baking sheet. Top with meat and cheese. Broil for about 5 minutes, until the cheese is melted and the chips have slightly browned on the edges. If the cheese is not melting, close the oven door for a few seconds but watch it closely so the chips don’t burn. Top with salsa, avocado, and olives.
