Start by preheating your oven to 350 degrees.

Now go ahead and begin preparing your bison top sirloin. Take your two steaks and begin cutting them into thin slices. Lightly season with salt, pepper, and garlic powder. Once sliced and seasoned you will place into a frying pan and cook until browned.

While that is cooking go ahead and take your bell peppers and onion and cut those into thin long slices. In a separate frying pan you will saute these until soft.

Now you’ll cut your slider buns in half and place the bottom half of the buns in a greased casserole dish. Don’t pull the buns apart, this makes it easier to put the sliders together.Next, mix the mayo and Dijon mustard together in a small bowl. Then spread the sauce over the cut side of the bottom buns.

Now it’s time to layer. Place your cooked steak and your sauted onion and bell pepper mix onto the bottom buns. You can now cover these with about 4 slices of provolone cheese (feel free to add more if you like it extra cheesy!) Place the top buns on the cheese.

Now for the savory butter sauce. Mix together melted butter, Dijon mustard, Worcestershire sauce, onion powder, and poppy seeds in a small bowl. Then you’ll pour this delicious mixture all over the top of the rolls. You can use a basting brush to evenly cover the tops, but make sure you let the excess drip between your sliders to the bottom.

Then, cover the casserole dish with foil and bake the sliders for about 10 minutes. Carefully remove foil and bake for another 10 minutes, until the cheese has melted. (20 minutes of cooking time total.)You can now remove your sliders from the oven. Grab a sharp knife and cut the sliders apart. They’re best served warm, but room temperature is okay too.

Serve and Enjoy!
