Break up the corned beef with a fork. Take a similar sized can of Spam and cut it into small dice. Combine together which should give you about a cup of meat.
Add 1 tablespoon of fish sauce (reserved the other tablespoon), soy sauce, red chili powder. Stir well to coat all of the meat and set aside to marinade for about an hour.
When your meat has been marinated; in a separate bowl, beat 3 duck eggs with the remaining 1 tablespoon of fish sauce.
Add the marinated meat and jalapeno peppers. Stir fry until the meat begins to turn brown, about 3 minutes. Remove from heat.
In a 10-inch omelette pan, fry the egg mixture. When it is cooked on the pan side, spoon the meat mixture neatly into the center of the pan in a rectangular shape.
Fold the edges of the omelette over the meat to form a parcel. Flip it over and fry until sealed and the egg is cooked through.
Cut the omelette into four pieces and and serve with other snack foods; such as pad Thai, pad mi Korat, som tam.
