throw every vegetable you can find in the fridge into the steamer. While its cooking, make a cheese sauce. puree the vegetables when they are done and mix through the cheese sauce to make a pasta sauce and pour over what pasta they fancy.
My boys (2 and 4) absolutely love it and always have, ever since they were tiny.
Its a great way to use up odds and ends of vegies and my ds1 who won't eat 'bits' will always ask for seconds.
