Sausage and Pepper Sandwiches

Directions

1. In a 6-qt. stockpot, combine beer, prepared mustard and ketchup. Add sausages, sliced onion and, if necessary, water to cover. Bring to a simmer and cook, uncovered, until a thermometer inserted in sausage reads 160°, 10-12 minutes.
2. Meanwhile, in a large skillet, heat oil over medium heat. Add peppers and chopped onion; cook and stir until tender, 6-8 minutes. Stir in garlic and seasonings; cook 30 seconds longer. Remove from heat.
3. Remove sausages from beer mixture. Grill sausages, covered, over medium heat or broil 4 in. from heat until lightly browned, 1-2 minutes on each side. Cut each sausage lengthwise in half. Serve in buns with pepper mixture and brown mustard.
