Cook the noodles according to the package instructions. Drain and set aside.
In a large pot or Dutch oven, heat the vegetable oil over medium-high heat.
Add the beef or lamb pieces and cook until browned on all sides.
Add the chopped onion and minced garlic, and sauté until the onion is softened, about 5 minutes.
Stir in the chopped tomatoes, bell peppers, carrots, daikon radish (if using), eggplant (if using), and green beans.
Cook for another 5-7 minutes, until the vegetables start to soften.
Add the soy sauce, ground cumin, paprika, ground black pepper, and salt.
Pour in the beef or vegetable broth and bring the mixture to a boil.
Reduce the heat to low and let the soup simmer for about 20-30 minutes, or until the meat and vegetables are tender.
Divide the cooked noodles among serving bowls.
Ladle the hot soup over the noodles.
Garnish with chopped fresh cilantro or parsley.
Note: Lagman is a traditional Central Asian noodle soup that is hearty and full of flavor. The combination of meat, vegetables, and spices makes it a comforting and satisfying dish.
Enjoy your meal!
