Follow these simple steps to create flavorful Cowboy Breakfast Sliders:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C).
2. Cook the Sausage: In a large skillet over medium heat, crumble and cook the breakfast sausage until browned and cooked through. Drain any excess grease.
3. Whisk Eggs: In a bowl, whisk together the eggs, milk, salt, and pepper until well combined.
4. Scramble the Eggs: In the same skillet, melt the butter over medium heat. Add the egg mixture and cook, scrambling gently, until just set.
5. Mix Components: Stir in the cooked sausage and half of the shredded cheddar cheese into the scrambled eggs. Mix until combined and cheese is melted.
6. Prepare Slider Buns: Slice the slider buns in half horizontally. Place the bottom half in a greased baking dish.
7. Fill the Buns: Spoon the sausage and egg mixture evenly over the bottom halves of the slider buns. Top with jalapeños and the remaining cheddar cheese.
8. Cover with Top Half: Place the top halves of the buns over the fillings.
9. Bake: Cover the dish with aluminum foil and bake for 15 minutes. Then, remove the foil and bake for another 10 minutes or until sliders are golden and crispy on top.
10. Cool and Serve: Remove from the oven and let cool for a few minutes before slicing into individual sliders.
