1. In a large skillet, melt butter with the oil. Add the onion, celery and garlic and saute until soft and transparent.
2. Add tomato sauce and tomato paste and stir until smooth.
3. Add remaining ingredients and bring to slow simmer. Simmer for 30-60 minutes (or not at all depending on your taste and time frame).
4. Remove the bay leaf. If you like smooth sauce (as some kids do) puree with an immersion blender. Spread the sauce on your prepared pizza dough. Keep leftovers in the refrigerator and use with a week or two.
