Prepare the garlic, onion, mushrooms, and bell pepper. Garlic and mushrooms need to be minced; onion and peppers need to be sliced.
Pre-heat the oven to 350° F.
Slice the steak as thin as possible, slicing it against the grain (to retain tenderness) into thin strips for cooking. Be sure to leave as much of the fat as possible on the meat. Fat gives meat flavor, especially during the cooking process.
Heat bacon grease or olive oil in a large skillet, and sauté the garlic, onion, mushrooms, and bell pepper for about 10 minutes, or 'til softened. Then set aside.
Add the steak, salt, pepper, smoked paprika, and Worcestershire sauce to the skillet. Cook until the meat is almost done.
At this point, add the veggies back in with the meat, stir, and simmer 'til fully cooked.
Slice the Hawaiian Rolls in half, as a whole. You'll have the top layer of the rolls, and then a bottom layer.
Place the bottom layer of the rolls in a greased baking dish or baking sheet.
Spread the bottoms of the rolls with mayo.
Add a layer of provolone cheese.
Now add a layer of meat and vegetables. Tongs work great for this. Go ahead and pile up the meat and veggies, no skimping allowed.
Add a dollop of Cheez Whiz to every single slider.
Now add the top layer of rolls.
In a separate small bowl or glass measuring cup, mix together the melted butter, roasted garlic powder, and minced parsley.
Brush the tops of the rolls with the garlic butter mixture, and sprinkle with extra Italian parsley if desired.
Cover with aluminum foil to keep your rolls from browning too quickly, and bake at 350° F for about 10 to 15 minutes, or 'til the cheese is melted.
Then uncover and bake an additional 5 to 10 minutes or so.
And that's it! Serve while warm and enjoy!
