How to Make It
Mound the rice in a large bowl. Scatter the tuna, lettuce, shiso, onion and sesame seeds over the rice and drizzle on some of the Korean Chili Sauce. Season with salt and toss with 2 large spoons until evenly mixed. Drizzle a little sesame oil over the salad and serve.
Shiso, or perilla, is a fragrant, leafy Japanese herb with jagged edges. It is used as a flavoring and as a garnish in salads, sushi and cooked dishes. It has a gingery taste and a cinnamon-like aroma. Shiso is available at Asian markets from summer through fall.
