01 - Preheat oven to 400°F.
02 - Slice each chicken breast horizontally to create 6 even, thin fillets.
03 - In a mixing bowl, whisk together the maple syrup, Dijon mustard, soy sauce, olive oil, smoked paprika, black pepper, and salt until well combined.
04 - Add the chicken fillets to the marinade, turning to coat evenly. Let rest for 10 minutes at room temperature.
05 - In a large skillet over medium heat, cook the bacon slices until crispy, about 4-5 minutes per side. Transfer to a plate lined with paper towels to drain.
06 - Remove the chicken from the marinade, reserving the leftover marinade. In the same skillet or on a grill pan over medium-high heat, sear the chicken fillets for 3-4 minutes per side until cooked through and golden. Transfer to a plate.
07 - Pour the reserved marinade into the skillet and simmer over medium heat for 2-3 minutes until slightly thickened. Brush the reduced glaze generously over each cooked chicken fillet.
08 - If using cheddar, place a slice on each glazed chicken fillet and broil in the oven for 1 minute until melted and bubbly.
09 - Lightly brush the cut sides of each slider bun with softened butter. Toast in a skillet over medium heat until golden brown, about 1-2 minutes.
10 - Spread a thin layer of mayonnaise on the bottom half of each toasted bun. Layer with arugula, a glazed chicken fillet, a strip of crispy bacon, sliced red onion, and the top bun. Serve immediately.
