Wash and chop all the vegetables before cooking. Dice the onion, bell pepper, and tomatoes into small pieces. Finely chop the jalapeño carefully. Preparing ingredients first makes cooking the Easy Mexican Omelette Recipe much smoother.

Crack the eggs into a mixing bowl. Add milk, salt, and black pepper. Whisk everything together until smooth and slightly frothy. Mixing well helps create soft and fluffy eggs with better texture.

Heat olive oil or butter in a nonstick skillet over medium heat. Add onions and bell peppers first. Cook for about three minutes. Stir in jalapeño and tomatoes until everything becomes soft and fragrant.

Pour the beaten eggs into the skillet over the vegetables. Tilt the pan gently so the eggs spread evenly. Let the eggs cook quietly for one minute without stirring too much during cooking.

Sprinkle shredded cheddar cheese, cilantro, and sliced green onion over one side of the omelette. The cheese melts beautifully while the fresh herbs add bright flavor and freshness to every bite.

Use a spatula to gently fold the empty side of the omelette over the filling. Press lightly so it stays together. Cook for another minute until the cheese melts completely inside.

Slide the Easy Mexican Omelette onto a serving plate carefully. Add salsa and avocado slices on top if desired. Serve immediately while warm for the best flavor and soft texture.
