Preheat the oven to 350°F (175°C). Lightly grease a 7×11-inch baking dish.
Slice the Hawaiian rolls in half horizontally and place the bottom halves into the baking dish.
Pour about 2 tablespoons of melted cowboy butter evenly over the bottom halves.
Layer the scrambled eggs evenly, followed by beef sausage, turkey bacon, and shredded cheese.
Place the top halves of the rolls over the cheese and brush with another 2 tablespoons of melted cowboy butter.
Cover with foil and bake for 15 minutes, until the cheese is melted and bubbly.
Remove foil and bake for another 3–5 minutes until the tops are golden brown.
Slice and serve warm. Brush with remaining cowboy butter or serve it on the side for dipping to finish these Cowboy Breakfast Sliders.
