Place rack in center of oven, and preheat to 450 degrees. Remove pizza from packaging. Spread mustard evenly over pizza. Arrange brat slices on top of the mustard. Sprinkle with onions and peppers. Bake for 15-20 minutes, until cheese is bubbling and edges begin to brown. Remove from oven and let rest for 5 minutes. Cut, serve, enjoy the pizza and enjoy the game!
Optional Serving Tip: For the authentic tailgate party, consider serving brat condiments on the side for guests to add to their pizza slice, such as relish, saurkraut, cheddar cheese, etc.
Optional Cooking Method--Gas Grill: Wrap 2-3 bricks in foil. Place on center of grill grates, about 10 inches apart (this will act as a shelf to hold the pizza pan for cooking). Preheat grill to high or about 450-475 degrees. Place prepared pizza (above) on a pizza pan with holes. Place the pan on the heated bricks, close the lid and bake for 11-14 minutes, until crust edges begin to brown. Remove from grill and let rest for 5 minutes before cutting to serve. Go team!
