Preheat the oven to 350°F (175°C).
Using a serrated knife, slice the 12 Hawaiian rolls horizontally and place the bottom halves in a baking dish in a single layer.
Evenly spread 2 heaping cups shredded chicken over the roll bottoms, then lay the 4 ounces sliced provolone on top of the chicken.
Place the top halves of the rolls over the cheese and use a serrated knife to cut between each slider to separate them slightly (cuts should go through the top but not all the way through the bottom).
In a small bowl, whisk together 2 tablespoons melted butter, 1 tablespoon Dijon mustard, 1 tablespoon honey, 1 teaspoon poppy seeds, and 1/4 teaspoon salt until combined.
Brush or spoon the glaze over the tops of the rolls, making sure some glaze gets between the cuts and on all exposed tops.
Bake for 20–25 minutes, until the cheese is melted and the tops are golden brown. Serve warm.
