Wanted: recipes for garden veggies

Alright I'm breaking the rules here and instead of posting a recipe I'm asking if anyone has a good spaghetti sauce recipe for canning. We have tomatoes, onions and peppers that need to picked from our garden and I've been reluctant to harvest because I don't know what to do with them now. Can you tell it's my first garden?! Any recipes or suggestions will be greatly appreciated.

Thanks!
