Mix meat, onion, bell peppers, bread crumbs, all the seasonings, Worcestershire or steak sauce and 2 tablespoons of the Meatloaf Topping.
Add eggs and shape mixture into a loaf. (If meatloaf is too wet or loose, additional bread crumbs may be added).
To serve conventionally, bake at 350 degrees for 30 to 45 minutes or until top is golden brown, then spread with remaining Meatloaf Topping and continue baking for 15 minutes or until a meat thermometer inserted in the middle of the loaf reaches 160 degrees. Serves 4 to 6.
Whisk together well all the topping ingredients. Reserve 2 tablespoons.
To grill for sandwiches: Reduce the first cooking time to 30 minutes, top with the meatloaf topping and continue cooking until the thermometer registers 145 degrees. Chill loaf immediately. When firm, cut into slices as needed and grill in a little olive oil until done and golden on both sides. Makes about 8 sandwiches.
