Boil the rice for 10 minutes, drain and place in a bowl along with the drained peas, corn and kidney beans. Drain and chop the tuna and add to the bowl. Add the mayonnaise completely. Mix everything and season with salt, pepper, paprika powder, possibly vegetable stock powder and garlic.
Parsley can be used for decorating.
The rice salad is ideal as a midnight snack for house parties.
