Add the microwaved onions, ground meat, and eggs to a bowl and knead. Add salt and pepper, and nutmeg if you have.
Fry on both sides in a frying pan. Wipe out the excess grease in the pan with a paper towel.
Add the onions and mushrooms. You don't need to saute them.
Squueze in the ketchup.
Add the water (or vegetable juice if you have it... this makes the flavor richer).
Cover with a lid without stirring and slowly boil over low-medium heat.
The moisture that comes out of the vegetables will turn the sauce into a tomato sauce. Simmer to reduce it down to your desired consistency.
I added coffee cream as the finishing touch.
Story Behind this Recipe
I was so surprised when my friend told me her way of making-simmered hamburger steaks, by just adding lots of ketchup! But they're really delicious. I had been using canned tomato sauce up until then...This not only tastes like a restaurant-quality dish, it's really easy to make too!
Make the hamburgers with as much meat and vegetables as you like. You cover with a lid and stew, but make sure to take the lid off halfway through if you are using lots of water and check it.
