Tuna mayo onigiri is a quick Japanese rice ball recipe that turns warm short grain rice, canned tuna, and creamy mayonnaise into a simple 15 minute meal. The filling usually combines drained tuna with Japanese mayo, soy sauce, black pepper, sesame oil, or a little salt for a rich savory taste. Warm rice is lightly salted, shaped around the tuna mayo filling, and wrapped with nori so each bite has soft rice, creamy tuna, and crisp seaweed flavor. This sea chicken rice ball is easy to prepare for lunch boxes, snacks, picnics, quick breakfasts, or light dinners because it uses pantry ingredients and simple shaping. The final onigiri is filling, portable, and comforting, pairing well with miso soup, pickles, tamagoyaki, salad, or other Japanese side dishes.
