Spam musubi

Spam musubi is a snack and lunch food composed of a slice of grilled Spam sandwiched either in between or on top of a block of rice, wrapped together with nori in the tradition of Japanese onigiri. Inexpensive and portable, Spam musubi are commonly found near cash registers in convenience stores or mom-and-pop shops all over Hawaii, the Marianas[citation needed] and Hawaiian Barbecue restaurants in the mainland United States. Musubi can be easily made with the right materials, and typically only uses spam, rice, some salt, nori and shoyu . In Hawaii, musubi with spam from a can or homemade luncheon meat is eaten as a snack or served in formal restaurants.
