Over medium heat, add 1 tsp of extra virgin olive oil (or avocado oil) to a pan. Swirl the pan to allow the oil to evenly coat the entire surface.
Whisk 3 whole eggs together, then add it to the pan to form the base of the omelette. Allow the eggs to heat up for 2 minutes or just enough time for them to form and set.
Once the eggs are set, spread out the following ingredients on top of 1/2 of the omelette, so you can then flip the other side of the egg over top of the mixture: 1/3 cup of chopped onion, 1/3 cup chopped red bell pepper, 1/3 cup of chopped tomato, 1/2 cup diced ham, and finally 1 cup of spinach for some greens.
Pat down all the ingredients, then allow it to cook for another minute.
Next up is the most challenging part of making an omelette, especially if you are cooking in a deeper pan. I’m referring to the flipping or folding of the omelette, without breaking it. Do your best to fold the empty half of the omelette on top of the full half, to complete the omelette.
Top the omelette with a dash of sea salt and black pepper, then allow the omelette to finish cooking for another minute.
