In a large glass salad bowl, place chopped lettuces. Spread cabbage over lettuces in a single layer.
In a separate bowl, combine carrots, radishes, celery, cauliflower, bell pepper, squash, peas or edamame, and red onion.
Whisk together olive oil, vinegar, mustard, garlic, soy, and sugar. Pour over chopped vegetables and mix well.
