more tomato sauce substitutes
- ketchup: use 1 cup of ketchup in place of 1 cup of tomato sauce. add spices to tweak the flavor as needed. a bit of basil is a good choice.
- tomato soup: add a 10 3/4-ounce can of tomato soup. then, cut one of the wet ingredients in the recipe back by 1/4 cup to account for the extra liquid.
