Bring ½ cup of rice and 1 cup of water with a pinch of salt to a boil. Once boiling, cover, reduce the heat to a simmer, and let it cook for approximately 11 minutes.

Give your vegetables a quick wash where needed. Cut your carrot and cucumber into matchsticks (or cirlces if easier). Cut your avocado into chunks.

Build your dish with rice as the base. Place watermelon tuna, edamame, cucumber, carrot, avocado, and purple cabbage on top. Garnish with spicy mayo and sesame seeds.
