I'm not sure what an actual Swiss steak recipe is. This isn't how my mom used to make it, so as far as I know, it's not the norm.
1-2 lbs round steak
1 can condensed Campbells Golden Mushroom soup.
beef stock, I have used the condensed beef stock as well as the containers, you can control the thickness of the dish by using the condensed
1 medium can diced tomatoes, drained
1 medium onion cut into medium pieces.
1 green bell pepper cut into thick strips
skinny egg noodles
Place the steak in a large pot with soup, beef stock, and 2 cans of water. Add onions. Simmer for about 20 minutes. Add diced tomatoes, green peppers, season with pepper, garlic powder and salt. Continue to simmer for another 30-40 minutes or until pepper is the consistency/crunchiness you prefer.
You can add more water to thin the broth or add cornstarch to thicken it. This is a matter of preference.
Serve with skinny egg noodles
