Cook spaghetti noodles by boiling in 5 quarts water for 8-10 minutes, drain and set aside.
Heat an oiled skillet over medium heat and add ground chuck, onions, and mushrooms. Break up the meat into small pieces as it starts to cook.
Cook until meat begins to brown and onions start to turn translucent, drain excess liquid, leaving meat, onions, and mushrooms cooking in pan.
In a separate bowl mix garlic powder, oregano, chili powder, Worcestershire sauce, red wine vinegar, ketchup, and one can of tomato sauce.
Add the mixed sauce to the meat and simmer on medium to low heat for 15 minutes.
In a large mixing bowl combine the second can of tomato sauce, cream of mushroom soup, cooked meat sauce, shredded cheese, and noodles. Mix well.
Transfer the mixture into a 15" casserole dish and top evenly with the crushed Ritz crackers. Use a knife to cut a few slits throughout the casserole. Pour the milk over the top, making sure not to overfill the dish.
Bake in a 350 degree Fahrenheit oven for about 45 minutes, or until the casserole is bubbly and the crackers begin to brown.
Let rest for 10 minutes before serving.
Notes
**Our family loves to top the cooked casserole with a drizzle of ketchup!
