• Preheat oven to 350 ℉ and grease a 9×13 baking dish
• Place a large skillet on the stovetop over medium-high heat. Add 1 pound lean ground beef, 1 teaspoon salt and/or your favorite seasonings, and 1 onion, diced and cook until meat is browned and onions are golden. (We aren’t making patties here, you want the meat to be crumbled.) Stir in 1 can Mild Rotel, drained and 1-2 tsp minced garlic until well combined.
• Slice 12 Hawaiian rolls or slider buns horizontally and place bottom half of buns in prepared pan. Top with meat mixture and then layer 12 slices sharp cheddar cheese on top. Add the top layer of the rolls.

Make the glaze

• In a microwave safe bowl, melt the 1/2 cup (8 tablespoons) salted butter. Add in 2 tbsp brown sugar, 1 tbsp worcestershire sauce, 1 tbsp mustard and whisk together until smooth. Pour over the buns & top with 1 tbsp sesame seeds .
• Cover the dish with foil and let sit for 10 minutes for the glaze to absorb. *Or if you're making these ahead of time, cover and refrigerate several hours up to overnight. Remove from the fridge at least 30 minutes prior to baking.*
• Bake for 25 minutes covered, then remove the foil and bake for another 5-10 minutes until the cheese is melted and the tops of the buns are golden and toasty. Watch carefully, each oven is different.
