Olive oil cooking spray
8 slices prosciutto
4 tilapia fillets (about 4 to 5 ounces each)
Salt and freshly ground black pepper, to taste
2 tablespoons olive oil
2 roasted red peppers from the jar, drained, patted dry and finely diced
4 toothpicks
Preheat oven to 400 degrees. Lightly coat a rimmed baking sheet with cooking spray.
Arrange four slices of prosciutto evenly spaced on the baking sheet. Place a second slice over each of the first four. Set one tilapia fillet over pair of prosciutto slices.
Season the fish with salt and pepper, then drizzle each with about 1/2 tablespoon olive oil. Spoon a quarter of the diced red pepper over each fillet, using the back of the spoon to spread it evenly.
Starting at one end of each fillet, carefully roll it up, holding the prosciutto so that it wraps around the outside of the fish. Poke a toothpick through the center of each roll to help it hold together.
Bake 20 to 25 minutes, or until the flesh feels firm and flakes easily.
