Rinse and thoroughly pat the chickpeas dry with a paper towel to ensure maximum crispiness.
Place the chickpeas, hemp hearts, chickpea flour, parsley, cilantro, garlic, cumin, coriander, salt, and pepper into a food processor.
Pulse the mixture until it is well combined and forms a coarse, moldable dough, being careful not to over-process into a paste.
Using your hands, shape the mixture into 4 or 5 small, even patties.
Heat the olive oil in a non-stick skillet over medium heat.
Place the patties in the skillet and sear for 3 to 4 minutes per side until they are golden brown and have a firm, crispy exterior.
While the falafel cooks, whisk together the Greek yogurt, tahini, and lemon juice in a small bowl until the sauce is smooth and creamy.
Lay the fresh baby spinach on a plate as a base.
Top the greens with the hot falafel patties and drizzle the zesty tahini sauce generously over the top.
