1. Cook one potato in water for 5 minutes (it should cook a little, but not become too soft).
2. In a frying pan, add a little avocado oil. Then add the partially cooked potato, diced ham, and diced tomato. Stir and cook until the ham is golden and the potato finishes cooking.
3. Create a space in the center and add one or two eggs. Cover the pan and cook until the egg whites are set.
