1 can (14 ounces) sauerkraut or fermented cabbage, rinsed and well drained
3 tablespoons spicy brown mustard
1 tablespoon brown sugar
12 uncooked bratwurst links or hotdog/sausage
1 bottle (12 ounces) dark beer
12 hoagie buns or hotdog bread, split
In a large skillet, cook bacon over medium heat until crisp, stirring occasionally. Remove with a slotted spoon; drain on paper towels.
Cook and stir onion in bacon drippings until softened. Reduce heat to medium-low; cook 15-20 minutes or until deep golden brown, stirring occasionally. Add apple and garlic; cook 2 minutes longer. Stir in sauerkraut, mustard, brown sugar and cooked bacon.
Transfer to a 13x9-in. disposable foil pan. Arrange bratwurst over top. Pour beer over bratwurst. Place pan on grill rack over medium heat; cook, covered, 30-35 minutes or until sausages are no longer pink. Remove pan from heat.
Remove bratwurst and return to grill. Grill, covered, 2-3 minutes on each side or until browned. Serve on buns with sauerkraut mixture.
