Place first 3 ingredients in a large microwave-safe glass bowl, and cover tightly with plastic wrap; pierce plastic wrap with a fork several times to vent. Microwave at HIGH 8 to 9 minutes or until vegetables are tender; drain. Press between layers of paper towels to remove excess moisture.
Stir together cooked vegetables, Cheddar cheese soup, and next 5 ingredients until well blended; spoon into a lightly greased 11- x 7-inch baking dish. Sprinkle evenly with cheese.
Bake at 450° for 20 minutes or until lightly browned.
