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.

PAM® Original No-Stick Cooking Spray

1 pkg (6 oz each) baby spinach leaves

1/4 teaspoon ground black pepper
6 dry lasagna noodles, uncooked

    Great idea to spray the slow cooker first. I might have to try this as using the Hunt’s in the crockpot sounds so much easier!

    This looks delicious! I love spinach and mushrooms in my lasagna. And making it in a crockpot would be so nice! Definitely pinning to try.

    That’s what I am missing. Italian seasoning. I can still make this even though I don’t have a slow cooker. Just have the burner down really low. :o)
