01 - Preheat oven to 400°F. Line a baking sheet with foil and lightly grease with cooking spray or oil.
02 - Slice chicken breasts in half horizontally to create thinner cutlets, then cut into 8 equal-sized pieces to fit the buns.
03 - In a mixing bowl, whisk together the maple syrup, Dijon mustard, soy sauce, olive oil, salt, and pepper until fully emulsified.
04 - Add chicken pieces to the bowl with the glaze, tossing to coat evenly. Allow to sit for 10–15 minutes to absorb flavor.
05 - Lay bacon slices on the prepared baking sheet. Bake for 12–15 minutes until crisp. Remove and drain on paper towels.
06 - Heat a grill pan or skillet over medium-high heat. Cook marinated chicken pieces for 3–4 minutes per side until cooked through and nicely caramelized.
07 - Brush the cut sides of the slider buns with melted butter. Toast in a skillet or on the grill until golden brown.
08 - Layer arugula, cooked chicken, crispy bacon, and cheese slices onto the buns. Top with red onion if desired.
09 - Secure sliders with cocktail picks and serve immediately while the cheese is warm and melty.
