In a small bowl whisk together the rice wine vinegar, cilantro, soy sauce, sesame oil, wasabi and crushed red pepper. Add the avocado and crabmeat and stir gently to combine.
Sift the flour into a small shallow bowl. Roll the hearts of palm in the flour and lightly coat. Heat the oil in a small skillet and when hot but not smoking, sauté hearts of palm until crispy and golden brown, turning occasionally with tongs to ensure even browning, about 6 minutes. Remove the hearts of palm from the skillet and cut on the bias into 1/2-inch thick slices. Divide the slices between 6 salad plates and decoratively arrange. Top each arrangement of hearts of palm with a portion of the crabmeat and avocado salad, spooning some of the vinaigrette over the slices of heart of palm and serve immediately.
