I don't have amounts of everything because I modified this from one of the dishes at the Whole Foods Market. I read the ingredient list and made it at home, leaving out foods we can't have. It is easy to make. Just use as many vegetables as you want and put everything else in according to taste.
Cut squash in lengthwise pieces, not too thin. Cut broccoli and cauliflower in bite size pieces. Chop the leek. Steam everything lightly. They need to still be crunchy after cooking. Cool the veggies in ice water to prevent them from cooking any more. Drain and put in bowl. Chop the dill. Add salt and pepper and toss dill and oil with veggies. This dish tastes wonderful cold and will be great for summer.
