- 4 (4 ounce) fillets swai fish
- salt and ground black pepper to taste
- 1 lemon, thinly sliced and seeds removed
- 6 mushrooms, thinly sliced

- 2 tablespoons capers
- Preheat oven to 350 degrees F (175 degrees C). Arrange aluminum foil on a work surface and lightly spray cooking spray onto 1 side of each.
- Place 1 swai fish fillet onto the middle of each piece of foil; season with salt and pepper. Layer lemon slices, mushroom slices, onion slices, and capers onto each swai fillet. Fold foil over each swai fillet creating a packet. Place packets on a baking sheet.
