Place the bottom of your bread rolls in a baking dish that fits them snugly. Squeeze over some mayonnaise. Top with your sausage slices.
Heat a pan over low heat and add some butter. When it foams add your whisked eggs and season with salt and pepper. Keep moving the eggs around the pan (as if cooking an omelette). When your scrambled eggs are still a little wet remove from the heat and add to your tray of sliders. Try to ensure each bun has a good bit of egg in it.
Top with cheese and then the top bun.
For your glaze, mix together your butter, ketchup and sriracha. Brush the buns liberally.
