I love Italian food. I really LOVE anything dish with tomatoes. There is nothing better than a good red sauce. I have been working on my family tree the last few months, and am astonished that I don’t have any roots tracing back to Italy. How could that be? I wonder if there is any such thing as an honorary Italian.

    Hunts is my go-to because they have a no salt added line of tomatoes and a sugar free variety of sauce. When I am not feeling like making my own or I am out of homemade canned tomatoes these are my picks.

    This is so helpful. My daugter loves lasagna. It would help a lot to know I can just put it in the crock pot.
