I was invited to my girlfriends house for dinner. She made "homade" spaggetti. I said, "I love these meatballs" She said she makes them & Lets them simmer all day. Well my husband said he loved her meatballe. (because she worked so hard on them) We it turns out, "YEP" they were COOKED PERFECT, right out of the bag! LOL I've bought them since and yes we love the taste and ease!
