One Appetizer recipe with Chili powder, Mustard, Rice, Salami, Salt, and Spring onion (scallion) for No shellfish diet

Tuna paste bento

Tuna paste is ridiculously easy to prepare and makes a great no cooking bento, cutting the preparation time to less than 20 minutes, including rice cooking time! Now, that's what I would call cooking on the go! You can also use the tuna paste for a great tasting onigiri or sushi.
