Cook the noodles according to the package instructions. Drain and rinse under cold water to stop the cooking process.
Toss the noodles with 1 tablespoon of vegetable oil to prevent them from sticking together. Set aside.
In a large skillet, heat 1 tablespoon of vegetable oil over medium heat.
Add the thinly sliced onions and cook until they are soft and translucent, about 5-7 minutes.
Add the minced garlic and cook for another minute.
Add the cooked and thinly sliced horse meat (or beef) to the skillet. Season with salt and black pepper to taste.
Cook for about 5-7 minutes until the meat is heated through and the flavors are well combined.
Remove from heat and let it cool.
In a small bowl, combine the beef or horse meat broth, soy sauce, white vinegar, ground coriander, ground cumin, and chili powder (if using). Mix well.
In a large mixing bowl, combine the cooked noodles and the meat mixture.
Pour the dressing over the noodles and meat, tossing gently to combine until everything is evenly coated.
Transfer the naryn to a serving platter.
Garnish with chopped fresh cilantro or parsley.
Enjoy your meal!
