Boil the rotini noodles until done...(my family likes them just a little undercooked), let cool. In the meantime, finely chop the 2 small cucumbers, cut the cherry tomatoes in half, finely chop the black olives, the cauliflower, & the brocoli and put in a large container. Next after noodles having been cooled add those to the rest of the mixture in the container. Mix well then add the shredded cheddar cheese. Once all of that is mixed up I add the whole bottle of italian dressing to it. Mix well...you can buy a bigger bottle of the dressing if you want....it's just according to your taste.
Store in refrigerator until completley chilled & serve.
