Crack the eggs into a bowl and season with salt and pepper. Beat well to combine.
Step 2
Heat the olive oil in a skillet over a medium heat and add the beaten egg. Leave to settle and cook through. Once the omelette is set at the edges, use a spatula to ease the cooked egg away from the sides, allowing any uncooked egg to flow underneath.
Step 3
Flake the tuna into a mixing bowl along with the cream cheese. Thinly slice the scallions and add to the bowl. Season with black pepper and roughly mash together to combine.
Step 4
Transfer the omelette to a plate. Shred the lettuce and scatter over half of the omelette then spoon over the tuna cream cheese. Fold the omelette and slice in half to serve.
