Quick, easy and simple
Heat the grill then place the toast under the grill until one side is toasted.
Heat the beans in microwave but not too hot.
Turn the slices of toast so the toasted side is faced down. Butter both slices of toast and place beans on the bread so it is all covered. Place the grated cheese on top of the beans.
Place the toast back under the grill until the cheese has melted keeping the beans on the toast.
