Add all ingredients into a large bowl. Then use the chopper and run it through all ingredients until chopped to desired consistency. If you don't want to chop up your delicata squash and want to eat it whole, you can set them aside like I did in the photo above. Either way is fine.
Alternatively, you can chop everything finely on a cutting board then place in to a large bowl to dress. Or you can make this not a chopped salad but just a regular salad with toppings.
