Remove casings from bratwurst. Cook in skillet over medium-high heat, breaking up meat as needed, until cooked through and crumbly.

Preheat oven to 450 degrees.

Spread pizza crust with prepared pizza sauce. Sprinkle with oregano and garlic salt. Distribute sauerkraut evenly over crust. Mix cheese together and distribute evenly over pizza. Arrange bratwurst over crust and top with mushrooms, green peppers, onions and olives.

Bake in preheated oven 10-15 minutes, until cheese is melted and crust is lightly browned around edges. Cut into wedges. Makes 8 slices.
