Preheat over to 350˚F. Spray a 9x13 inch pan with cooking oil.
Slice rolls in half and lay the bottom part of the rolls in the bottom of the prepared pan.
Top the rolls with 8 slices of provolone cheese, ham, pepperoni, salami, and the the remaining cheese.
Place the top of the rolls on the cheese. Slice in between each individual roll.
To make the topping, in a microwave safe bowl, melt the butter for 30 seconds, stir, and cook in 15-second increments until melted. Add Worcestershire sauce, yellow mustard, and poppy seeds and mix well.
Brush the butter mixture over each roll.
Bake uncovered for 15-20 minutes or until the cheese is melted and the tops are golden brown. Serve immediately with a side of marinara sauce if desired.
Notes
Cut in between each roll before baking to make these sliders easy to serve!
Use balsamic vinegar as a substitute for Worcestershire sauce if needed.
You can also use Italian seasoning in place of poppy seeds if you find the Italian seasonings too overpowering.
