Wash the broccoli and chop it roughly into small pieces. Add the pieces to a food processor and pulse until the broccoli is slightly larger than rice. Transfer to a bowl.
Chop the kale and transfer it to a separate bowl. Add 2 tbsp of lemon juice and massage for 5 minutes until tender. Transfer to the same bowl with the broccoli.
Finely chop the parsley and onion and add them to the same bowl. Mix and set aside. Start making the dressing.
Slice the avocado open and scoop out the flesh of one half into a blender. Add the garlic clove, lemon juice, greek yogurt, 2 tbsp of olive oil, and 1/4 tsp each salt and pepper. Blend until smooth.
Drizzle the sauce on top and toss. Garnish with hemp seeds and serve.
