I love the homemade play-doh! So much softer than the 'real' stuff. I also have a recipe for homemade flavored instant oatmeal - that's a big hit at our house
I'm a mom, too, and I really identify with your post. It's so easy to get lazy when you're so busy. But I'm learning, like you, that a little food prep planning can go a long way towards curbing impulse fast food purchases. You should check out recipezaar.com - I love that I can search it for recipes using lists of ingredients I already have in the pantry.
