Prepare frozen chicken tenders according to package directions.2 Once the tenders are done, reduce the oven temperature to 350°F.
While the chicken is baking, whisk mayonnaise, Dijon mustard, and honey together in a small bowl.
Line a quarter sheet pan with non-stick aluminum foil. Cut the rolls in half horizontally, keeping them connected as one sheet, and place the bottoms on the prepared pan. Spoon some of the sauce over the bottom half of the rolls, spreading it so it covers the entire surface.
Place five slices of Swiss cheese on top of the sauce, breaking one of the pieces in half so the buns are covered in a single layer. Next, place four or five slices of deli ham, folded in half, on top of the cheese slices in a single layer. Then, place the cooked chicken tenders in a single layer on top of the ham slices. Next, place four or five slices of deli ham, folded in half, on top of the chicken in a single layer. Then, place five slices of Swiss cheese on top of the ham, breaking one of them in half so that it's in a single layer.
Spoon some sauce onto the inside of the top buns and place them on top of the cheese. Melt unsalted butter in a small microwaveable bowl. Then, stir in garlic powder and dried parsley. Brush the mixture over the tops of the Chicken Cordon Bleu Sliders. Bake in a 350°F oven for 20 minutes, or until the cheese is melted and the tops are golden brown.
Remove from the oven and allow to cool for about five minutes before cutting into individual sliders. Serve with additional sauce on the side.
