In a large saucepan cook the rice according to the instructions on the packaging.
While the rice is cooking, begin cutting the avocado and cabbage into slices, julienne the carrots, and cube the mango and cucumber.
If you're using frozen edamame, thaw them in a mug of hot water.
Bring a small frying pan to a high heat with a the olive oil. Sear the tuna for 1 minute each side for a rare steak (or longer depending on your preference), turn the heat off and move the pan to the side. Leaving the tuna to stay warm while preparing the bowl.
Drain the rice and split between 4 bowls.
Place the cucumber, carrot, edamame, mango, cabbage, avocado around the edges of the bowls. It looks better if you seperate out the colours if you can!
Take the tuna off the heat and slice on a chopping board. Place across the middle of the bowls.
If you feel like it you can drizzle a little lemon/lime juice or soy sauce over the top of the bowl (if you're going for either fresh or asian inspired flavours).
Enjoy!
