Preheat your oven to 425 degrees.

Season mahi mahi with salt and pepper, to taste.

Brush each mahi mahi filet with olive oil.

Wrap each piece of fish in a square of foil by folding the top and bottom and creating a tee-pee with the sides of the foil. Crimp the top to keep it together.

Bake for 12-14 minutes, until the fish is flaky and cooked thoroughly.

Spread the pineapple salsa over each mahi mahi fillet prior to serving.
