In a small bowl, mix drained tuna with mayo, sriracha, celery, spring onion, salt, and pepper. Set aside.

Lay out the tortilla wraps and place a pinch of lettuce in the center of each.

Add the spicy tuna mixture, followed by sliced avocado, a pinch of salt and pepper, and Doritos arranged in a circular shape.

Sprinkle with cheddar cheese, then fold the edges of the wrap over the center, working around until fully enclosed.

Heat a large frying pan over medium heat. Place each wrap seam-side down and cook for 3-4 minutes until golden and crispy.

Flip and cook the other side until golden brown.

Slice in half and serve hot!
