Pizza in a Pot
In a large skillet cook sausage and onion over medium heat until meat is brown and onion is tender. Drain off fat. Place cooked meat mixture in a 3-1/2- or 4-quart slow cooker. Stir in pizza sauce, undrained tomatoes, stir-fry vegetables, and mushrooms.
Cover and cook on low-heat setting for 6 to 8 hours or on high-heat setting for 3 to 4 hours.
Arrange bread, cut sides up, on a large baking sheet. Broil 3 to 4 inches from the heat for 1 to 2 minutes or until golden. Spoon meat mixture on top of bread slices. Sprinkle with pizza cheese. Broil for 1 to 2 minutes more or until cheese melts. Cut into 10 pieces.
