Make the dressing: Transfer the red wine vinegar, hemp hearts, nutritional yeast, mellow miso, garlic, chives, parsley, lemon juice, and water to the canister of a blender. Blend on high until smooth.
For serving: Place the red onion, bell pepper, capers, sun-dried tomatoes, artichoke hearts, cabbage, white beans, edamame beans, lentils, cucumber, and parsley into a large bowl. Add two-thirds of the dressing and mix to combine. Add more dressing as desired.
For meal prep: Use three to four (24 to 32-ounce) jars with tight-fitting lids. Add one-third of the dressing to each jar followed by the bell peppers, red onion, artichoke hearts, cabbage, sun-dried tomatoes, capers, edamame, white beans, and lentils. Omit the cucumber if stored overnight.
