Grill bratwurst, covered with grill lid, over medium-high heat (350° to 400°) for 10 to 15 minutes or until thoroughly cooked, turning once.
Melt butter in a large skillet over medium heat; add onion and bell pepper strips, and sauté until tender.
Stir in beer and seasoning blend; add sausage, and simmer mixture for 20 minutes.
Place 1 bratwurst link in each roll, and top evenly with vegetable mixture. Serve with Special Mustard Sauce.
Note: For testing purposes only, we used Mrs. Dash original blend.
