How about some fresh marinara?

Too many for sandwiches, too few to can.

Marinara

1 T. olive oil
1 medium onion, diced
1 T. minced garlic
2 T. tomato paste (you might could get away without it)
2 c. diced tomatoes
1 c. water
1 t. sugar
1/2 t. salt
grind in some fresh pepper
1 t. dried basil OR 2 T. fresh basil chopped

Heat the oil and cook the onion and garlic until the onion is soft.
Add the tomato paste and heat through.
Add the rest of the ingredients (except the fresh basil), cover the pot loosely and cook about 20 minutes.
Taste and adjust the seasonings if needed. Add the fresh basil.
Leave it alone if you like a chunky sauce. I prefer to puree it with immersion blender for a smoother texture. Makes maybe 4 servings.
