01 - Preheat oven to 400°F. Line a baking sheet with aluminum foil and lightly grease the surface.
02 - Slice each chicken breast in half horizontally, then cut into 8 equal-sized portions for even cooking.
03 - In a mixing bowl, whisk together the maple syrup, Dijon mustard, soy sauce, olive oil, salt, and pepper until well combined.
04 - Toss the chicken pieces in the maple glaze, coating evenly. Allow to rest for 10 to 15 minutes.
05 - Arrange bacon slices on the prepared baking sheet and bake for 12 to 15 minutes until crisp. Transfer to paper towels to drain excess fat.
06 - Heat a grill pan or skillet over medium-high heat. Sear the marinated chicken pieces for 3 to 4 minutes per side until fully cooked through and nicely caramelized.
07 - Brush the cut sides of each slider bun with melted butter. Toast on a skillet or grill until golden brown.
08 - Layer arugula, a piece of glazed chicken, a strip of crisp bacon, a slice of cheese, and thinly sliced red onion on each bun bottom. Cap with the bun top.
09 - Secure each slider with a cocktail pick and serve warm.
