Bring a large pot of lightly salted water to a boil.

Heat 2 tablespoons the olive oil in a large skillet over medium heat. Add green pepper and cook 2 minutes. Add garlic and anchovies and cook for 1 minute, mashing anchovies with spoon.

Add tomatoes, salt and pepper. Cook 5 minutes, stirring.

While sauce is cooking, prepare pasta following package directions. Drain, reserving 1 cup cooking water.

Toss pasta with tomato mixture and remaining tablespoon olive oil. Add 1/4 cup pasta water if needed. Serve with cheese.

Note: If desired, use a 6-ounce can of tuna instead of anchovies.
