We don't eat spaghetti too often but when we do I use ground turkey meat and purchase the Prego heart smart mushroom spaghetti sauce. I've just been saving the jars and Wallah! We now have a set of new glasses. They are great for drinking water out of because they're so large. I don't use any other cup for my son's smoothie's now because these jars spill so much less than a normal glass or cup. He can actually carry it through the living room without any splashing or spilling out. Yes, his smoothie is a sort of brown color. I've been throwing in a handful of baby carrots and two large kale leaves. He has no idea that there is as much veggie in his daily smoothie now as there is fruit.
Maybe everyone has been using spaghetti sauce jars for glasses forever but this is new to me and I'm rather happy about it. I love these glasses! And, bonus: if one breaks I'd have no reason to get upset in the least. I could just make spaghetti for dinner the next night, haha!
