"This is a great vegetarian alternative! Use vegetable stock instead of beef if you want it to be truly meat free. This soup is full of flavors: sweet, salty, sour, and bitter. It's great for a chilly night."
Heat 2 tablespoons oil in a large saucepan over medium heat. Add bok choy stems, white parts of green onions, and garlic. Cook until softened, about 3 minutes. Stir in beef stock, mushrooms, miso soup mix, and soy sauce. Bring to a boil; simmer over low heat.
While the broth is simmering, heat remaining 1 tablespoon oil in a skillet over high heat. Add tofu; cook until golden brown, about 5 minutes. Pour in hoisin sauce and toss to coat. Remove from heat.
Stir bok choy leaves and ramen noodles into the broth mixture. Turn heat to high and boil until noodles are cooked, 3 to 5 minutes. Serve topped with tofu and eggs.
