Add your farro or barley to a medium pot. Add enough water to cover by about 2-inches. Bring to a boil, then reduce your heat and simmer rapidly for about 20-30 minutes, or until tender. Drain and set aside.
In a large bowl, add the egg and whisk thoroughly. Add the lamb, almond four, dill, garlic, salt and pepper and use clean hands to mix thoroughly. Form in about 20 tablespoon-sized patties.
In a large cast-iron or non-stick skillet, warm the olive oil. Add the patties and cook until browned, about 2-3 minutes. Fip and repeat on the other side.
In a medium bowl, toss together the cucumber, radish, onion (if using), vinegar and salt. Set aside.
In a small bowl, mix together the yogurt, lemon, garlic (if using), and salt.
Serve the meatballs with the cucumber radish salad and warm cooked grain. Top with yogurt sauce, herbs, nuts, and a squeeze of lemon. A drizzle of olive oil and back pepper add a nice finish!
