Peel and slice the potatoes thinly, then soak them in cold water to remove excess starch.

Thinly slice the onion and ham. Ensure all ingredients are evenly sliced for a uniform omelette.

Heat 2 tbsp of oil in a pan over medium heat. Add the potatoes and sauté until partially cooked.

Add the sliced onion and ham to the pan. Season with salt and pepper, and continue to cook until ingredients are 80% cooked.

In a bowl, whisk the eggs with minced garlic. Add the cooked ingredients and mix well. Adjust seasoning with additional salt and pepper if desired.

Heat a small frying pan over low heat with a bit of oil. Pour the omelette mixture into the pan and shape the top with a spatula.
