Wash and dry the fresh produce.
Trim and cut green onions crosswise into thin pieces. Place half in a medium bowl. (Reserve remaining green onions for serving.)
Drain tuna, add to the bowl with the green onions, and flake with a fork.
Add mayo, chili-garlic sauce, soy sauce, oil, and salt to the bowl. Stir to combine and set aside.
Thinly slice jalapeño pepper into rings; seed and remove ribs with a spoon to reduce spice level. (Be careful with jalapeños; do not touch your eyes and ensure you wash your hands after handling or wear gloves while preparing.)
Halve and pit avocado; using a spoon, scoop out the flesh and slice crosswise into thin half-moons. Season with salt.
Separate the lettuce into leaves.
To serve, pile lettuce leaves, in stacks of two per wrap, onto plates; fill with avocado and tuna salad. Top with reserved green onions and jalapeño. Enjoy!
