Why This Recipe Works

To give tuna the tortilla treatment, we turned to the taco's open-faced cousin, the tostada; we love the contrast of this fish's buttery texture with the crispy shell, and its pretty pink color provided visual appeal on top. A sesame crust added extra crunch and served as a jumping off point for a tostada with Asian-inspired ingredients. Slices of the seared tuna rest on a bed of delicate napa cabbage shreds, tossed in a soy sauce, fresh ginger, and sesame oil vinaigrette. For side slaw, we often salt our cabbage in advance but since tostadas are eaten right away, we tossed the cabbage with the dressing just before assembling the tostadas to easily avoid water-logged slaw. A spicy, creamy, tangy component comes in the form of a sriracha mayo. A sprinkling of thinly sliced scallions finishes with bright green color.
