Start by preparing all the ingredients, cut the vegetables and fruit.
Fill a large bowl with warm water and dip a rice paper wrapper into the water, wait a few seconds, and transfer it to a working surface, like a cutting board.
Lay the vegetables on the bottom 1/3 of the rice paper wrapper. Layer them on top of each other. Start by adding the lettuce, carrot, cucumber, mango, sliced avocado, and one mint leaf.
Roll them out, fold the lower edge over the filling, then fold the sides, and finally, roll it up. Remember to tuck the filling in as you go. Repeat this with all spring rolls.
Finally, cut them in half and serve with your favorite dipping sauce.
