Heat 1/2 tbsp butter or oil in a small non-stick skillet over medium heat. Add the sausage patty and cook for 3-4 minutes per side, until golden brown and cooked through. Remove from skillet and set aside on a plate.

Crack the egg into a small bowl and whisk briefly with a fork, adding a pinch of salt and pepper. Reduce heat to medium-low in the same skillet (add a tiny bit more butter if needed). Pour in the whisked egg.

Let the egg cook for 1 minute until the edges begin to set. Using a spatula, gently fold the egg into a square or round shape to fit the muffin. Cook for another 1-2 minutes, then flip and cook for 30 seconds more until set.

While the egg is cooking, toast the English muffin to your desired crispness.

Place the cooked egg onto the bottom half of the toasted English muffin. Immediately top with the cheese slice so it begins to melt.

Add the cooked sausage patty on top of the cheese. Cover with the top half of the English muffin. Serve immediately and enjoy your Sausage Egg Cheese Breakfast Sandwich!
