In a food processor, pulse together the chickpeas, parsley, cilantro, garlic, cumin, coriander, baking powder, salt, pepper, and flour until a coarse mixture forms.
Form the mixture into small balls or patties, about 1-2 inches in diameter.
In a large skillet, pour enough oil to cover about 1/2 inch deep and heat it over medium heat until shimmering.
Carefully add the falafel balls in batches to the hot oil, cooking for about 3-4 minutes on each side until golden brown.
In each bowl, start with a base of cooked quinoa (or brown rice) and layer a handful of mixed greens.
Top your greens with the golden falafel, cherry tomatoes, cucumber, red onion, pickled radishes (if using), and avocado slices.
Finish each bowl with a generous drizzle of tahini sauce.
