MAKE THE SPICY TUNA
To a bowl, add the finely diced tuna along with mayonnaise, sriracha, soy sauce, sesame oil, lime juice, and sliced green onions. Mix together.
SPICY MAYO
To make the spicy mayo, mix together mayo, sambal, sriracha, sesame oil, sugar, and lemon juice in a small bowl. Once it's creamy and smooth, set aside.
MAKING THE WONTON CUPS
Preheat oven to 350°F.
Spray a muffin tin with oil and add 1 wonton wrapper into each cupcake and press down to form a cup. Spray the top as well and pop in the oven to bake for about 6 to 9 minutes, or just until golden and crispy.
Take out of the oven and add the spicy tuna in the cup, about two tablespoons or so. Add toppings you like such as avocado, spicy mayo, sesame seeds, cilantro, green onion, etc. Enjoy.
