In a large nonstick skillet, cook bacon over medium-high heat until crisp, about 10 minutes. Remove bacon, and let drain on paper towels. Wipe skillet clean.
Spread pepper jelly onto one side of half of bread slices; top with cheese, bacon, arugula, apple, pepper, and remaining bread slices.
In same skillet, melt 2 tablespoons butter over medium heat. Add 2 sandwiches; cook until cheese is melted and bread is toasted, 3 to 4 minutes per side. Repeat with remaining 2 tablespoons butter and remaining 2 sandwiches. Serve immediately.
