Equipment

  • 1 medium mixing bowl
  • 1 fork or whisk
  • 1 Cutting board
  • 1 Knife
  • 1 nonstick skillet with lid
  • 1 spatula
  • 1 large plate for flipping

Ingredients
  

  • 3 large eggs
  • 1 5- oz can tuna drained well
  • 1 small yellow onion finely chopped
  • 1 medium tomato diced small
  • 1 cup shredded mozzarella cheese
  • ¼ cup all-purpose flour
  • 2 tablespoon fresh cilantro chopped
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 1 tablespoon olive oil for the skillet

Instructions
 

  • Crack the eggs into a medium mixing bowl and beat them with a fork or whisk until the yolks and whites are fully combined.
  • Add the drained tuna to the bowl and gently break it apart with a fork so it mixes evenly into the eggs.
  • Add the chopped onion and diced tomato. Stir well until the vegetables are evenly distributed throughout the egg mixture.
  • Add the shredded mozzarella cheese, salt, and black pepper. Mix again until combined.
  • Sprinkle in the all-purpose flour and add the chopped cilantro. Stir until the mixture becomes thicker and all ingredients are well incorporated.
  • Place a nonstick skillet over medium-low heat and add the olive oil. Spread the oil across the bottom of the skillet.
  • Pour the tuna and egg mixture into the skillet. Use a spoon or spatula to spread it into an even layer.
  • Cover the skillet with a lid and cook for about 10 minutes, or until the bottom is set and lightly golden.
  • Carefully slide the omelette onto a large plate. Place the skillet over the plate and flip the omelette back into the pan so the uncooked side faces down.
  • Cook for another 5 minutes, or until the second side is golden and the center is fully cooked.
  • Remove from the heat, transfer to a serving plate, slice, and serve warm.
