Apple, White Cheddar, Bacon, & Hot Honey Grilled Cheese

Add oil to a skillet over medium heat and caramelize the thinly sliced onions for 5 minutes. Spread a thin layer of mayo on the outside of each slice of bread. Layer the white cheddar, apple slices, bacon, caramelized onions, spinach, and a drizzle of hot honey inside the sandwiches. Cook the sandwiches in the skillet for 5-8 minutes, or until the cheese is melted and the bread is golden brown. Remove from skillet and enjoy!
