Cook the chicken filets according to package instructions. (The air fryer gives the best crispy texture!)
Preheat your oven to 350°F.
Slice the slider rolls in half horizontally to create a top and bottom layer.
Arrange the bottom buns on a baking sheet or oven-safe dish.
Place the cooked chicken filets evenly across the bottom buns.
Spoon marinara sauce over the chicken.
Lay the cheese slices on top to cover all 12 rolls.
Add the top buns, and brush with melted butter if desired.
Bake for 5 minutes, or until the cheese is melted and everything is warmed through.
Cut into individual sliders and serve warm.
