01 - Preheat oven to 400°F (200°C). Line a rimmed baking sheet with aluminum foil and lightly grease the surface.
02 - Slice the chicken breasts in half horizontally, then cut each portion into equal pieces to yield 8 cutlets total.
03 - In a mixing bowl, vigorously whisk together the maple syrup, Dijon mustard, soy sauce, olive oil, salt, and pepper until fully emulsified.
04 - Submerge the chicken pieces in the maple mixture, ensuring they are thoroughly coated. Allow to rest for 10 to 15 minutes.
05 - Arrange the bacon slices in a single layer on the prepared baking sheet. Bake for 12 to 15 minutes until crispy. Transfer to a plate lined with paper towels to drain.
06 - Place a grill pan or large skillet over medium-high heat. Sear the marinated chicken cutlets for 3 to 4 minutes per side until fully cooked through and nicely caramelized.
07 - Brush the cut sides of the slider buns with melted butter. Toast face-down in a hot skillet until golden brown.
08 - Layer the bottom buns with arugula, followed by a grilled chicken piece, a slice of crispy bacon, a slice of cheese, and red onions. Cap with the top buns.
09 - Insert cocktail picks through the center of each slider to hold the layers intact. Serve immediately while warm.
