Spicy kani salad is a popular Japanese-style salad made with imitation crab meat (kani), cucumber, avocado, and various other ingredients mixed together with a spicy mayo sauce. The imitation crab meat is usually shredded and mixed with a creamy dressing made from mayonnaise, Sriracha hot sauce, and sometimes other ingredients like soy sauce, sesame oil, or rice vinegar to give it a tangy, slightly sweet flavor. The dish is often served as an appetizer or side dish at Japanese restaurants and is known for its refreshing and spicy taste.
