I used a homemade sauce. I cook large in part by taste, rather than measurement, but roughly, the ingredients are:
1 can crushed tomatoes
2 cans diced tomatoes (Leaving one can as is, and draining, then pureeing the second)
1 part each Onion and green pepper to 1/2 part each red pepper and celery. Fresh garlic to taste (Pureed, then sauteed in olive oil. About 3-4tbsp of the puree is used.)
1/4 tsp Salt
1/4 tsp White pepper
2tsp Oregano
1tsp Basil
1 1/2 tsp Fennel seed
1/2 tsp Thyme
2tbsp Brown sugar
