If you don't have a spiralizer you can still make and enjoy the flavors in this salad. You can use a grater, a peeler or simply just cut the veggies into diced pieces. If you want to use a peeler it will work best on the carrot and zucchini but it really won't work on the beets. The grater will work on all three veggies but you don't really get the long pieces like you do with the spiralizer. Last, you can cut the beets and carrots into small diced pieces and roast in the oven though they may take longer to cook. Here's what I would do without a spiral to make this salad. I'd dice up the beets and carrots into small pieces, 1/2 inch or smaller and cook for 20-30 minutes. Then I'd use a peeler to make zucchini ribbons to add to the final salad.
