Could you tell me how to prepare Spanish Omelette?
Here's a recipe for Spanish Omelette:

Ingredients:

• 1 onion, thinly sliced
• 3 potatoes, thinly sliced
• 2 cups olive oil
• 6 eggs
• 1 pinch salt

Instructions:

1. Heat up the olive oil in a really hot pan.
2. Thinly slice the onion.
3. Slice the potatoes into 3-millimeters thick pieces.
4. Fry the vegetables in the olive oil over high heat for 10-15 minutes until they caramelize.
5. Drain the vegetables and save the olive oil for later use.
6. Add 6 eggs to a bowl and whisk. Add the fried vegetables, stir, and leave to set for 15-20 minutes.
7. In a nonstick pan, fry the egg mixture over high heat for 1 minute, then reduce to a low heat for 2-4 minutes.
8. Cover the pan with a large plate and carefully turn the omelet out onto the plate.
