Potato Omelette

This is my version of the classic Spanish omelette.
Ingredients:
1 no small baking Potato (cubed)
1 no Onion (chopped)
3 no Eggs
1 tbsp butter
1 tsp minced Jalapeno/green chilly
2 tbsp milk
Salt to taste
Pepper to taste.
Method:
Beat the eggs with salt,pepper,jalapeno,milk and set aside.
Preheat the oven to 350 degrees F.
Heat the butter in an oven proof pan and saute the onions for a minute.
Now add the cubed potatoes and continue sauteing until the potato is almost done.
Now pour the egg mixture and spread evenly, let it cook for about a minute or two.
Remove the pan from the burner and place it in the preheated oven and let it cook for 11-15 minutes or till the eggs are done.
Remove from oven and serve immediately.
