My Mother In Love would fix these with meatloaf when she was feeling in a festive mood. She told me it originally came from her mother's Favorite Betty Crocker cook book. Mom played with it, and made it her own. She used olive oil instead of butter, and added the garlic and water chestnuts. As well as cooking the peas in the mushroom liquid. So the family dubbed them Party Peas. They are very quick to make, colorful, and tasty.
