Hi - you might try this veggie topped pizza out - especially if you are fond of ranch dressing.

I mix a small box of Mori-Nu Tofu, soft, with 1 envelope of Hidden Valley Ranch fat free dressing and use that as the base rather than a tomato base. Then top it with broccoli buds, cauliflower buds, and carrots. I steam the carrots, since they take longer to cook. I use the frozen broccoli buds and cauliflower buds defrosted and drained and place this in a ready made pizza crust. You can add mushrooms if you want. This has no cheese and my husband really enjoys this occasionally as a different pizza than the ordinary run of the mill kind.
