Steam the following veggies until almost cooked through:

1 zucchini sliced
1 yellow squash sliced
2 cups broccoli cut to desired size
2 cups cauliflower cut to desired size
2 large carrots cut

Other veggie options: bell peppers, mushrooms, whole green beans, asparagus, etc. etc. etc. Go hog-wild. (If you want to skip all the cutting you could even just buy the pre-cut frozen stuff.)

Drain veggies, and put into casserole dish
Drizzle 1/2-1 cup of fat free Italian dressing (depending on how many vegetables you have) and toss veggies to coat.
Sprinkle 1 oz part skim mozzarella cheese over the vegetables
Sprinkle 2 tbs of bread crumbs over the top of the cheese

Pop into the oven at 400 just to melt the cheese.

Enjoy!
