Tamagoyaki Sandwich

Step 1

In a bowl, whisk together the 4 eggs, 1 tbsp sugar, 1 tsp soy sauce, and 1/4 tsp salt until just combined, about 30 seconds.

Step 2

Heat 1 tbsp vegetable oil in a nonstick skillet over medium heat. Pour in half the egg mixture, tilting to spread evenly.

Step 3

When the egg is set but still soft, about 2 minutes, roll it to one side of the pan. Add the remaining egg mixture, lifting the roll to let it flow underneath.

Step 4

Cook until the new layer is set, about 2 minutes, then roll the whole omelette into a log. Remove from heat and let rest for 2 minutes.

Step 5

Spread 1 tbsp butter on the 2 slices of bread. Place the lettuce leaves on one slice, then slice the tamagoyaki into 4 pieces and layer them on top.

Step 6

Close the sandwich with the other bread slice, press gently, and cut in half. Serve immediately.
