This recipe has been discussed here before and, again, it's one of those things you just throw together and let cook for a while.
Here's the blueprint:
box of chopped tomatoes
can of tomato paste
red wine (lots for the sauce, more for the cook)
spices from the garden
Basically, fry up the bacon, hamburger and onions. Toss into a large pot with the rest of the ingredients. Stir and cook for a while. Adjust the seasonings to make it hotter or saltier or whatever. Thicken with corn flour and water. Serve over spaghetti.
It's an easy favorite at our house and sometimes we add smoked sausage just for fun. This batch turned out very dark because the wine used was a Cabernet Sauvignon from Chile.
