Whisk together maple syrup and Dijon mustard in a small bowl to create the glaze.
Season sliced chicken breasts with salt and pepper.
Heat olive oil in a large skillet over medium-high heat and cook chicken for 4 to 5 minutes per side until the internal temperature reaches 165 degrees Fahrenheit.
Apply the maple-mustard glaze to the chicken during the final 2 minutes of searing to caramelize.
Preheat oven to 350 degrees Fahrenheit.
Arrange slider bun bottoms on a lined baking sheet.
Layer each bun bottom with a portion of glazed chicken, a piece of bacon, and a half-slice of Gouda.
Place bun tops over the cheese and brush the surface with melted butter.
Bake for 10 minutes or until the cheese is thoroughly melted and the buns are golden brown.
