2 Tbsp olive oil
2 lb onions, thinly sliced
1 1/2 Tbsp red wine vinegar
1 Tbsp dark brown sugar, packed
1/2 tsp caraway seeds
3 cooked smoked sausages (such as white bratwurst or chicken-apple)
4 slice rye or pumpernickel bread
4 tsp dijon mustard
4 oz gruyere or emmenthal cheese, thinly sliced
3 Tbsp butter, room temperature

Steps:

1. Heat 2 tablespoons oil in heavy large skillet over medium-high heat. Add onions and saute until slightly softened, about 5 minutes. Stir in vinegar, sugar and caraway seeds. Reduce heat to medium-low and saute until onions are deep brown and very tender, about 20 minutes longer. Season to taste with salt and pepper. (Can be prepared 2 hours ahead. Let stand at room temperature. Rewarm over low heat before using.)
2. Preheat broiler. Brush 11x7-inch metal baking pan with oil. Place sausages in pan. Broil until sausages are brown and crisp, about 6 minutes per side. Transfer sausages to work surface and cut lengthwise in half.
3. Arrange 3 sausage halves on each of 2 bread slices. Spread 2 teaspoons mustard over sausages on each. Top sausages with caramelized onions, dividing equally. Top with Gruyère or Emmenthal cheese slices, dividing equally. Cover with remaining 2 bread slices. Spread half of butter over upper bread slices.
4. Heat large nonstick skillet over medium-low heat. Carefully invert sandwiches, buttered side down, into skillet. Cover and cook until bottoms are brown, about 5 minutes. Spread remaining butter over upper bread slices. Turn sandwiches, cover and cook until bottoms are brown, about 4 minutes longer.
