Preheat oven to 350 degrees. Crack the eggs into a mixing bowl. Add in milk, onion powder, and salt and pepper. Whisk together. Scramble eggs in a large skillet over medium heat until cooked through.
Cook the sausage patties in a large skillet over med heat, about 4-5 minutes per side or until cooked through.
Slice the Hawaiian rolls horizontally, without pulling them apart. Place the bottom half in a 9x13 baking dish. Arrange the scrambled eggs over the top, followed by the cooked sausage patties. Place cheese slices on top of the sausage, and place the top half of the buns on top.
In a small bowl, whisk together the melted butter, maple syrup, and sriracha until well combined. Brush evenly over the sliders covering the top and sides. Bake in preheated oven for 20 minutes.
Allow to cool slightly for a couple minutes. Slice into 12 equal sliders, and serve.
If you're worried about the spice from the sriracha, it really does not come through as spicy. These are more sweet that anything else. You get a hint of the flavor of sriracha, without the spice. You can certainly omit it if you wish!
The recipe calls for 6 slices of cheese vs. 12 because the size of slices I use each covers two of the sandwiches, so just use however many slices it takes to cover all the sliders!
If you have leftovers, they can be re-heated without getting soggy. Preheat the oven to 300 degrees, and warm in the oven for about 10-12 minutes or until warmed through.
