To make summer rolls, place one rice paper round in hot water to cover, soften 30 to 60 seconds until limp and pliable.Place on damp towel, lay lettece leaves down covering paper, in a single layer leaving a boarder around free of lettece. On one edge spoon some crab salad top with seasoned noodles, then a couple slices of avacado. Pick up end and roll folding in edges as you go and rolling gentle but tight, like a egg roll.
