Yes, you can use a few different vegetables in these tots. Broccoli is a great choice because you can chop up the broccoli florets really small, and they make for a good binding vegetable. Cauliflower makes for a great tot as well. If you're not a fan of cauliflower, I would also suggest that you could use zucchini or spinach if broccoli isn't your favorite vegetable. If you plan on using zucchini, use a peeler to shave off thin slices of the zucchini and then chop those up really small and then squeeze any excess water out. You can also use a food processor to do the work.
