Prepare. Preheat your oven to 350. Prep a 9X13 baking dish for nonstick.
Bread. Remove the rolls from the packaging whole taking care to not separate them. Then slice the rolls horizontally in half. Place the bottom half of the rolls into your prepared baking dish.
Mayo. In a small bowl, use a whisk or a fork to combine together your mayonnaise and mustard. Use a butter knife or small spatula to evenly spread the mixture over the rolls in the baking dish.
Layer. Place your cheese slices over the rolls and then top the cheese slices with the ham slices.
Top. Place the top half over the rolls on top of the ingredients, again without breaking up the individual rolls.
Topping. In a microwave-safe bowl, melt your butter, stopping to stir every 30 seconds, until melted. Then carefully use a whisk or a fork to mix in the worcestershire sauce and the seasoning. Lastly, use a pastry brush to brush this topping over the tops of the rolls.
Set. Loosely cover the rolls with foil and let them sit for five minutes for the buttery topping to seep into the rolls tops.
Bake. Bake your sliders for 10 minutes with the foil on so that the cheese can get soft and gooey. Carefully remove the foil. If the tops are not golden brown you can continue to bake for a couple of minutes so that the tops turn golden brown and a bit crisp.
Serve. Serve your sliders warm.
