To add cheese to scrambled eggs, start by whisking the eggs in a bowl until they are fully combined. Next, heat a nonstick skillet over medium heat and add a small amount of butter. Once the butter is melted and the skillet is hot, pour in the whisked eggs. As they start to cook, use a spatula to push the eggs from the edges of the skillet towards the center, allowing the uncooked eggs to flow to the sides and cook. Just before the eggs are fully cooked, sprinkle grated cheese over the top and continue cooking until the cheese has melted and the eggs are fully set. Finally, serve the scrambled eggs hot with a sprinkle of fresh herbs or a slice of toast.
