M.T.
I make pasta and carrots for my kids. I find a fun-shaped pasta, and when it is almost done I toss in some frozen carrots (or veggie of choice). When it is all done, I spray a little butter on it, and they eat it up every single time.
Something else that is good is to put a can of cream of chicken soup on the pasta. Or ranch dressing and parmesan cheese. You can use spaghetti sauce and mottzerella cheese...the possibilities are endless. Maybe you could set out a variety of toppings and let the kids "dress up" their pasta any way they want.
