This time I made half meat sauce as per recipe - without the red beans, and added 1 can Steak n Shake chili. The reason I tried this - the original recipe was not really that much like S&S...and the store bought canned chili is not identical to restaurant chili.
The combination of the two worked.
I also topped off the sauce over the spaghetti with tbsp ketchup.
