Ingredients
  

  • 12 slider buns (Hawaiian or plain, split)
  • 8 large eggs
  • 1/4 cup milk or unsweetened almond milk
  • 12 ounces breakfast sausage or ground turkey sausage (casings removed if using links)
  • 6 slices cheddar or pepper jack cheese (or 1 1/2 cups shredded)
  • 1/2 cup egg whites (optional, boosts protein)
  • 1/2 small red onion, finely diced (optional)
  • 1 small red bell pepper, finely diced (optional)
  • 2 cups baby spinach, chopped (optional)
  • 2 tablespoons olive oil or avocado oil
  • Salt and black pepper, to taste
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon smoked paprika (optional)
  • 2 tablespoons unsalted butter, melted
  • 1 tablespoon Dijon or yellow mustard
  • 1 teaspoon honey or maple syrup (optional, for balance)
  • 1 tablespoon sesame seeds or everything bagel seasoning (optional topping)
  • Nonstick cooking spray

Method
 

  1. Prep the pan and buns: Heat the oven to 350°F (175°C). Lightly spray a 9x13-inch baking dish. Slice the buns horizontally as a slab, keeping tops and bottoms intact. Place the bottom slab in the dish.
  2. Cook the sausage: Warm 1 tablespoon oil in a skillet over medium heat. Add sausage and break it up with a spatula until browned and cooked through, 5–7 minutes. Season with a pinch of salt, pepper, and smoked paprika. Transfer to a plate.
  3. Sauté veggies (optional): In the same pan, add remaining oil. Cook onion and bell pepper until softened, about 3–4 minutes. Stir in spinach until wilted, 30–60 seconds. Remove from heat.
  4. Scramble the eggs: In a bowl, whisk eggs, egg whites (if using), milk, garlic powder, and a pinch of salt and pepper. Pour into a lightly oiled nonstick skillet over medium-low heat. Gently push the eggs from edges to center until just set and still soft, 3–5 minutes. Avoid overcooking.
  5. Assemble the layers: Spread the scrambled eggs evenly over the bun bottoms. Top with sausage, then the sautéed veggies. Lay cheese slices over the top in an even layer.
  6. Add the tops: Place the bun tops over the filling, pressing gently to settle everything.
  7. Mix the glaze: Stir melted butter with mustard and honey (if using). Brush the tops generously. Sprinkle sesame seeds or everything seasoning if you like.
  8. Bake: Cover loosely with foil and bake 10 minutes. Uncover and bake another 5–8 minutes, until the tops are lightly toasted and the cheese is melted.
  9. Slice and serve: Let rest 3 minutes. Cut into 12 sliders with a serrated knife. Serve warm.
