Prepare the biscuits and sausage patties according to their package or recipe instructions; keep warm.
Crack the eggs into a mixing bowl and whisk until combined; season with salt and pepper to taste.
Heat 1 tablespoon butter in a skillet over medium heat until melted and foamy.
Pour the whisked eggs into the skillet and let them sit undisturbed for a few seconds, then gently stir from the edges toward the center; continue stirring occasionally until eggs are almost set, then remove from heat.
Split each biscuit in half, place a sausage patty on the bottom half, top with scrambled eggs and a quarter piece of cheddar, then close with the top half of the biscuit.
Serve the sausage, egg, and cheese biscuits immediately while warm.
