You don't have to follow exact measurements for this salad - add a lot of chopped chicken and just a little bit of veggies for color, or make a mostly veggie salad with just a little bit of chicken.
To grate the veggies, use a hand-held cheese grater or a food processor with a grating disc.
If you're not going to eat the salad right away, keep the dressing separate from the salad and toss before eating.
Veggie chicken salad will stay fresh for up to 5 days in the refrigerator, but the texture gets softer.
