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.

    Out of all the things I have made in the crockpot, lasagna has not been one of them. I am going to give this a try, just without the mushrooms.

    I have had lasagna cooked in the slow cooker but I’ve never cooked it myself. I’ll have to try it out though.
