In a bowl, mix olive oil, smoked paprika, garlic powder, onion powder, dried thyme, salt, black pepper, maple syrup, apple cider vinegar, Dijon mustard, and red pepper flakes to create the marinade.
Coat the chicken breasts in the marinade and refrigerate for at least 30 minutes (up to 2 hours for more flavor).
Cook the marinated chicken in a non-stick skillet over medium-high heat for about 4-6 minutes per side until cooked through.
Prepare the beef bacon until crispy.
Toast slider buns with melted butter on cut sides.
Assemble each slider with sauce on the bottom bun, followed by chicken, cheese (optional), beef bacon, lettuce, tomato slices, and any desired toppings.
