Marinate the tuna fillets overnight in the Sweet Chili Ginger Dipping Sauce. Heat 2 tablespoons of sesame oil in a saute pan and add the udon noodles. Toss to heat through, then add Yuzu Syrup. Toss again, then season to taste with salt and pepper.
Heat the remaining 4 tablespoons sesame oil until smoking in a separate saute pan. Remove tuna fillets from the marinade and generously season all sides with salt and pepper. Carefully place the fillets into the hot pan. Sear all sides of the fillets, 2 minutes for rare. Remove from the pan.
To serve, in the center of each plate place some udon noodles. Slice tuna fillets in half, on the bias, and place on udon noodles. Arrange Green Papaya Salad over top of tuna and serve.
