Venison Swiss Steak ?

I've never been to Switzerland and I didn't consult any other recipes or resources for this but I'm going to call it Swiss Steak anyway.

Ingredients
2 round steaks, deboned (venison)
1 onion, sliced
1 container tomato sauce (I used some PC marinara sauce or something, about 1 - 1.5 cups)
1 same container of water (to cover everything)
1.5 cups frozen peas

noodles with olive oil, garlic, oregano, salt and pepper (I used whole grain spaghettini)

Directions

1. Place steaks, onion, sauce and water in slow cooker and cook for 6 hours on high.
   
2. Break up the meat with a couple of forks, run the frozen peas under hot water to thaw them a bit and stir them into the slow cooker. Let simmer while you cook the pasta.
   
3. Cook pasta, dress with olive oil and/or butter, finely chopped garlic, oregano, salt and pepper.
   
4. Serve meat over pasta.
