1Preheat oven to 350F. Line a 9×9-inch or 9×13-inch pan with aluminum foil, spray with cooking spray; set aside.
2Using a large serrated knife, slice the rolls in half so you have a ‘slab’ of tops and a ‘slab’ of bottoms; don’t pull the rolls apart and slice individually because you want to keep them connected.
3Place the bottom ‘slab’ of rolls in prepared pan.
4Evenly layer about half of the ham over the rolls.
5Evenly layer the cheese.
6Evenly layer the remaining ham.
7Add the top ‘slab’ of rolls; set aside.
8To a medium microwave-safe bowl, add the butter and heat on high power to melt, about 1 minute.
9Add the mustard, poppy seeds, onion, Worcestershire sauce, salt, pepper, and whisk to combine.
10Evenly and slowly pour the butter mixture over the rolls. Use a spatula to spread the mixture over the tops. Some of the mixture will pool at the base of the rolls.
11Cover with aluminum foil and allow rolls to stand at room temp for about 5 to 10 minutes.
12Bake covered for about 20 minutes or until cheese has melted.
13Uncover and cook for about 3 to 5 minutes, or until as done as desired. Baking time will vary based on the size of pan used, climate and oven variances, etc. Bake until as done as desired; watch to make sure they don’t burn since all ovens and ingredients vary.
14Slice into individual sliders and serve immediately. Sliders are best warm and fresh.

Tips
Do not pull the rolls apart and slice individually; keep them connected as a 'slab'.
Allow rolls to stand at room temperature for 5 to 10 minutes after pouring the butter mixture to allow it to soak in.
Baking time will vary, watch to make sure they don’t burn.
Sliders are best warm and fresh; leftovers will keep airtight in the fridge for up to 4-5 days.
To reheat leftovers, microwave gently for about 30 seconds.
Swiss cheese can be substituted with other sliced cheeses like cheddar, mozzarella, Monterrey Jack, Pepper Jack, or gouda.
Poppy seeds add texture and should not be omitted; Everything But the Bagel Seasoning can be used as a substitute if needed.
To prepare in advance, cut and layer the rolls, ham, and cheese, cover, and refrigerate. Add the butter mixture just before baking to prevent soggy rolls.
