FILL wide bowl with warm water. Working one at a time, dip rice paper into water for a few seconds, until just soft and then transfer to work surface.
ARRANGE lettuce leaves on the bottom third of the rice paper. Layer turkey, carrots, cucumber, avocado, basil and cilantro leaves on top of lettuce.
ROLL rice paper over filling, rolling away from you, tucking in sides as you roll.
TRANSFER to serving plate, seam-side down and repeat with remaining rice paper and fillings.
COMBINE chili sauce, lime juice, sriracha and soy sauce in a small bowl. Season with additional sriracha to taste.
SLICE spring rolls in half and serve with dipping sauce.
