Season each crawfish with the paprika and crab boil seasoning. Dredge each crawfish in the cornstarch, and then shake off any excess. Fry crawfish in a hot, greased skillet for only 45 seconds, so as to not overcook it.
For each taquito, lightly butter and warm the tortilla. Drizzle 2 teaspoons hoisin sauce over the entire toasted tortilla, and then sprinkle with 1 teaspoon sesame seeds. In the center of the tortilla, layer the 2 tablespoons romaine, 1/2 tablespoon red cabbage, and top with 1 teaspoon Habanero Onion Puree. Next, drizzle with 2 teaspoons Jalapeno Mayo and sprinkle with 1 tablespoon fried rice sticks. Place a slice of avocado and a crawfish on top of the mixture. Finally, drizzle the crawfish with 1 teaspoon sesame oil and garnish with a cilantro leaf. Repeat with remaining tortilla.
