Absolutely -- I definitely call on my momtourage for help with cooking. I've gotten great recipes (that I've never heard of) that are delicious, quick to make and everyone eats. I've also gotten help from a couple of friends with strategies for picky eating. I've learned not to give too many choices -- it's peas or corn. Not, "What vegetable do you want?"
As for actual cooking, the local pizzeria and chinese place are considered part of my momtourage. ;) I'll call them up and have them deliver a great meal that everyone eats! :)
