Sausage-Potato Frittata

Coat a 10- to 11-inch nonstick skillet with nonstick cooking spray and heat over medium-high heat. Add potato mixture and peppers and cook 10 minutes, stirring occasionally. Add sausage and cook 5 minutes, stirring occasionally, or until potatoes and peppers are tender and mixture is golden-brown. Meanwhile mix eggs with salt and pepper in a small bowl. Reduce heat to low and pour eggs evenly over potato mixture. Cover and cook 9 minutes or until eggs are set. Sprinkle with cheese. Serve with tomato wedges.
