Place dried chickpeas in a small mixing bowl and cover with water. Allow to soak overnight in the fridge. After soaking, the volume of chickpeas will double to ~2 cups. When ready to make falafel, drain water and rinse.
Preheat the oven to 350 degrees Fahrenheit.
In a food processor, puree the tahini, oil, parsley, cilantro, spinach, onion, cumin, lemon juice, garlic, and paprika. Puree until greens are finely chopped, you want it to have the consistency of pesto.
Add the chickpeas and pulse until mixture starts to stick together and chickpeas are minced, but not yet pureed. (You don't want to make hummus!)
Use a spoon out bean mixture and use your hands to form into ~21/2 inch patties. Place patties on a baking sheet.
Bake falafel for 30-40 minutes or until lightly browned.
To make dill yogurt sauce, stir together all the ingredients until well mixed.
