Ingredients
8 slices of bacon
1/2 tsp kosher salt
4 slices Swiss cheese
4 oz Brie cheese, thinly sliced
2 firm, but ripe, pears, sliced
4 Tbsp butter, softened
2 cups onions, chopped
8 slices hearty bread

Instructions
Heat a large skillet over high heat. When hot, add the bacon and cook until brown and crispy. Remove bacon from pan and place on paper towels to drain.

Remove all but 2-3 Tbsp of bacon fat from the pan and add the onions. Sauté on high heat for 2 minutes, then reduce to medium-high heat and cook until onions are dark brown in color, about 5 minutes. Remove from skillet and set aside.

Assemble each sandwich by spreading 1/4 of the onion mixture on a piece of bread. Add the Swiss cheese, pear, 2 slices of bacon, 1 oz of Brie and another slice of bread. Butter outsides of the sandwich and grill on medium heat until golden brown, about 3 minutes per side.
