Polenta with Sausage and Peppers

Remove broiler pan; line broiler-pan rack with foil (for easy cleanup). Heat broiler. Brush both sides of polenta with the oil, then arrange on foil-lined rack. Heat a large nonstick skillet over medium-high heat. Add sausage and cook, breaking up chunks with a wooden spoon, 5 minutes or until browned and cooked through. Remove with slotted spoon to a bowl. Remove all but 1 Tbsp fat from skillet. Add bell pepper and onion and sauté 5 minutes or until tender. Meanwhile broil polenta 4 minutes or until lightly colored and hot. Add tomatoes and sausage to skillet. Cook, stirring, until heated through. Serve on polenta.
