1. Begin by combining the maple syrup, Dijon mustard, garlic powder, and black pepper in a bowl. Add the thinly sliced chicken breasts and ensure they are well-coated with the marinade. Cover and refrigerate for at least 30 minutes, allowing the flavors to meld and the chicken to absorb the sweet and savory goodness.

2. While the chicken is marinating, cook the beef bacon slices in a skillet over medium heat until they reach the desired level of crispiness. Remove the bacon from the skillet and place it on paper towels to drain any excess fat.

3. Preheat your oven to 375°F. Slice the slider buns in half horizontally and place the bottom halves on a baking sheet. Layer a slice of crispy bacon and a portion of the marinated chicken slices onto each bottom bun.

4. Place the assembled sliders in the preheated oven and bake for 10-12 minutes, or until the chicken is cooked through and the buns are lightly toasted.

5. Remove the sliders from the oven and, if desired, top each one with a few fresh arugula or spinach leaves. Place the top halves of the buns on and serve the Maple Chicken & Bacon Sliders warm, ready to be savored and shared.
