Add oil to a heated frying pan and cook the onions. Once they've turned translucent, add the wieners, salt, and pepper, and continue to cook.
Flavor the ingredients. Add the ketchup, Worcestershire-style sauce, sugar, and soy sauce, and mix so that all the flavors are absorbed. Add some more salt and pepper here.
Add the rice and margarine to the ingredients from Step 2. Remove the frying pan from the heat and stir until the margarine melts. Once melted, return the pan to the heat.
Once everything has heated through, it's finished. I recommend using this for omurice or cream-based doria.
Here it is in omurice.
Story Behind this Recipe
My mother often made this when I was young. It only had onions, but it was delicious even when it was cold, so I loved it. It seems like this was a dish made from leftovers until payday at the end of the month, so we often had it towards the end of the month. At that time my family didn't really eat out, so I felt it was a real treat.
Soy sauce is a multi-functional secret ingredient for restaurant-like dishes. It goes especially well with rice, so definitely use it with rice dishes. The margarine at the end coats the rice with oil for a soft, chewy feel. Mincing the onions makes this easier to eat.
