Companion Mun Cha'i Ya, also known as Peking Vegetarian Roast Duck, is a vegetarian dish that replicates the flavors and textures of traditional Peking roast duck without using meat. Instead, it typically features wheat gluten (seitan) that is seasoned, marinated, and roasted to achieve a crispy exterior and tender texture reminiscent of duck meat. The dish is known for its savory and aromatic profile, often enhanced with a blend of soy sauce, hoisin sauce, and Chinese five-spice seasoning. Companion Mun Cha'i Ya is a popular choice among vegetarians and those looking to explore meatless alternatives while enjoying the rich flavors of Chinese cuisine.
