Preheat the oven to 350° F and spray a thin layer of olive oil on two baking sheets. Slice the wonton wrappers diagonally to create triangles.
Arrange the wonton wrappers on the baking sheet in a single layer and bake on the middle rack for 8 minutes. Lightly spray the wonton wonton wrappers with olive oil and place them back in the oven for 4-6 minutes or until golden brown and crispy. You can add a small pinch of salt to the wonton chips after spritzing them if you like.
While the wonton chips are baking, make the poke sauce. In a medium bowl add the minced garlic, grated ginger, mirin, soy sauce, lemon juice, toasted sesame oil, rice vinegar, and the thinly sliced white parts of the scallions. Mix until combined, then add the finely diced tuna and toss to coat. Place in the refrigerator to marinate for 10-15 minutes. I like to prepare the remaining ingredients while the tuna marinates.
When the wonton chips are finished, add them to a serving plate and top with marinated tuna, diced pineapple, sliced jalapeño, diced avocado, sesame seeds, and the green parts of the sliced scallions. Drizzle with spicy mayo and serve.
Sushi grade tuna will keep in the fridge for about 24-48 hours before it goes bad.
