Cut the squash into quarter circle slices ½" thick. Toss in salt and place in a colander to drain for 15 minutes. This is called degorging, to remove excess water and soften the squash structure.
Toss the remaining ingredients in a large bowl together.
Rinse the degorged squash in running water, drain and pat dry. Add to the dressed ingredients and refrigerate, allowing to meld flavors together for at least 30 minutes.
Serve as a side dish or with grilled meat as a main course.
