Preheat the oven to 425 degrees F. Line a baking sheet with parchment.Add the lamb, onion, garlic, lemon zest, parsley, cumin, oregano, cayenne, and a pinch each of salt and pepper to a bowl. Coat your hands with a bit of olive oil, and roll the meat into 2 tablespoon size balls (will make 10-12 meatballs), placing them on the prepared baking sheet. Transfer to the oven and bake for 15-20 minutes or until the meatballs are crisp or cooked through on the inside.Meanwhile, make the goddess sauce. Combine all ingredients in a blender and blend until smooth and creamy, adding water, 1 tablespoon at a time as needed, to thin the sauce. To serve, spread the hummus and goddess sauce on plates. Add the orzo, meatballs, feta, cucumber, tomatoes, and greens. Drizzle olive oil and lemon juice lightly over top of everything. Enjoy!
