Lay out two tortillas on a large cutting board. Divide the lettuce, tomato, corn, avocado slices, green onion and tuna between each tortilla.
Drizzle each wrap with 1 tablespoon of the dressing, reserving the rest for dipping.
Roll up each tortilla, tucking in the ends as you go.
Enjoy immediately with the extra chipotle ranch, or wrap in plastic wrap and keep in fridge for up to 3 days (for optimal freshness).
