My Best Spaghetti Sauce

We enjoy living on this.
It's very simple to make.
Simmer all day in slow cooker:
fresh garlic sauteed in extra virgin olive oil
3 large cans of crushed tomatoes
2 cans of chopped black olives
1 small can of tomato paste
3-6 stalks chopped celery
3-6 chopped carrots
2 bay leaves
basil
oregano
parsley
red chili pepper
optional: A splash of robust red wine if you have it.
It will taste even better the next day!
