Preheat the oven to 350°F Combine the lamb and beef in a large bowl. Set aside.
Heat the olive oil in a large skillet over medium-high heat. Add the onion, carrot, celery, garlic, and ginger and cook for about 5 minutes, or until the onion is translucent. Add the salt, paprika, cumin, curry powder, cayenne, cinnamon, and pepper. Cook for 1 to 2 minutes to release the flavors. Remove from heat and let cool for 10 to 15 minutes.
Stir the vegetables into the ground meat. Mix in the bread crumbs, eggs, cilantro, and mint. Transfer to a 1 1/2 quart loaf pan and set in a baking pan. Pour water into the baking pan to reach halfway up the sides of the loaf pan.
Bake the meat loaf for 1 1/2 hours, or until firm and cooked through. Let rest for 10 to 15 minutes. Unmold onto a plate and slice.
