Crack 3 large eggs gently into a medium-sized bowl.

Add milk and a little salt & pepper - whip eggs lightly using a fork.

Sitr in the tuna fish (or canned salmon) if you prefer.

Melt butter in a medium-sized skillet over medium-high heat.

Pour the egg mixture into the skillet and turn the heat to medium.

Using a spatula, push the cooking egg mixture around the skillet (add the cheese just after the eggs start to set) and continue cooking for about 2-3 minutes or until the eggs are cooked through.

Add additional cheese on top if desired before serving.
