1 can (14 ounces) sauerkraut, rinsed and well drained
1/2 cup sour cream
2 tablespoons stone-ground mustard
8 pita pocket halves, warmed
In a large skillet, cook bratwurst, onion and pepper over medium heat 8-10 minutes or until bratwurst is no longer pink and vegetables are tender, breaking up bratwurst into crumbles; drain. Stir in sauerkraut; heat through.
For sauce, in a small bowl, mix sour cream and mustard. Fill pita halves with bratwurst mixture; serve with sauce.
