Fresh Vegetable Omelet

Directions

1. In a small bowl, beat the egg whites, water and cream of tartar until stiff peaks form. In a large bowl, beat eggs and salt until thick and lemon-colored, about 5 minutes. Fold in the whites.
2. In a 10-in. ovenproof skillet coated with cooking spray, melt butter. Pour egg mixture into skillet. Cook for 5 minutes over medium heat or until puffed and lightly browned on the bottom. Bake, uncovered, at 350° for 10-12 minutes or until a knife inserted 2 in. from edge comes out clean.
3. Meanwhile, in a large skillet, saute the tomato, zucchini, onion, green pepper and Italian seasoning until tender. Carefully run a knife around edge of ovenproof skillet to loosen omelet. With a knife, score center of omelet. Place vegetables on one side and sprinkle with cheese; fold other side over filling. Slide onto a serving plate; cut in half.
