In a bowl, mix 2 tablespoons Kikkoman® Teriyaki Baste & Glaze and remaining burger ingredients together. Shape a level 1/2 cup measure into patties and refrigerate for 15 minutes to firm up.
Heat a nonstick skillet to medium heat. Brush the patties with a thin layer of oil, and sear on both sides. Begin brushing the 1/4 cup Kikkoman® Teriyaki Baste & Glaze onto the patties, flipping constantly for even cooking on both sides for 5 to 10 minutes, depending on desired doneness.
Spread a thin layer of Kikkoman® Wasabi Sauce on bottom bun and add a leaf of lettuce, followed by the grilled pineapple and tuna. Drizzle with more Kikkoman® Wasabi Sauce and place top bun.
