On paper, this sandwich makes very little sense…

Layer the Fillings: Delicately layer slices of ham, turkey, and Swiss cheese on each slider bun, building flavorful stacks of goodness.
Spread the Mustard-Mayo Sauce: Whisk together Dijon mustard and mayonnaise, then generously spread this delightful sauce over the cheese layer.
Top and Assemble: Complete your sliders by placing the top halves of the buns over the fillings, creating irresistible sandwich towers.
Prepare the Glaze: Combine melted butter, honey, Worcestershire sauce, poppy seeds, and dried minced onion to create a flavorful glaze.
Brush with Glaze: With a gentle hand, brush the glaze over the tops of the slider buns, ensuring an even coating for maximum flavor infusion.
Make the Egg Batter: Whisk together eggs, whole milk, Dijon mustard, salt, and pepper to create the perfect egg batter for dipping.
Dip and Bake: Carefully dip each slider into the egg batter, ensuring a thorough coating before returning them to the baking dish.
Bake to Golden Perfection: Slide your assembled sliders into the preheated oven and bake for 20-25 minutes, or until golden brown and deliciously melty.
Serve Warm: Once baked to perfection, remove your sliders from the oven, allow them to cool for a moment, and serve warm for maximum enjoyment.
