In a preheated frying pan with one tablespoon oil, sauté garlic and onions. Add corned beef and season with salt, black pepper, and sugar. Sauté the mixture until quite dry, then, remove from pan.

In a bowl, beat the eggs and mix the sautéed corned beef.

Preheat the frying pan again on medium heat and add 3 tablespoons oil. Pour half of the mixture ino the center of the pan making it into a round shape. Wait until one side has turned golden brown.

Get two round plates big enough for the omelet. Using your spatula, slowly slide the omelet to the plate with the uncooked side. Cover with another plate and flip. Then, slowly slide the half cooked omelet to the pan. Wait until golden brown to remove from the frying pan. Serve with rice and ketchup on the side.
