Hi I made your spaghetti sauce recipe this week and LOVED it!! By far the best I’ve ever made!!
This sauce was delicious!!! I love diced tomatoes in my sauce so i added diced tomatoes but it was amazing with or without.
Even perfect-er with sauteed mushrooms.
It even works when you accidentally use crushed tomatoes instead of tomato sauce. Chef’s Kiss
