A food container coupling system includes a food container configured to attach to a can or a beverage container lid/coupler. The food container includes a food compartment with a side wall and a bottom, which has a food compartment coupling structure. The food compartment coupling structure has an inner wall coupling structure with an inner wall jut, and is shaped complementary to the rim of a beverage can and when the food container is mounted to the beverage can, the food compartment coupling structure mates with the beverage can rim. The system may also include a beverage container lid/coupler with a coupling ring adapted to mate with the rim of a beverage container, wherein the rim defines a second plane, and a beverage container lid coupling structure extends from the second plane and can mate with the food compartment coupling structure.
