Preheat the oven to 400 degrees Fahrenheit.
In a food processor, pulse together the chickpeas, garlic, salt, pepper, nutmeg, paprika, and baking powder until roughly combined. Add the white beans, oats, lemon juice, and egg and pulse a couple of times. You want texture, so do not puree.
Using your hands or scoop, divide the bean mixture into eight pieces and shape into patties. Place on a lightly oiled baking sheet.
Bake in the oven for 20-25 minutes, until golden brown and crispy on the outside.
While the falafel is baking, whisk together the ingredients for the sauce together in a bowl.
Drizzle the sauce over the falafel and serve over greens or in a wrap.
