Peel the cantaloupe melon and mango, cut into slices, and then into matchstick-shaped pieces.
Hull and slice the strawberries into thin slices.
Quarter the apple and remove the seeds. Slice and cut into matchsticks as well, then squeeze a little lemon juice over to stop them from turning brown.
For the peach, cut it in half to remove the pit, then cut it like the other fruit.
In a large bowl, add warm water and soak the rice paper wraps for about 20 seconds. When it starts to go soft, remove them from the water. If the wrappers are too sticky to use, it means they spent too long in the water. The wraps should be pliable, but still slightly firm, as it will soften while you put in the filling.
Place the rice paper smooth side down on a chopping board. Place the fruit towards the middle of the wrapper and sprinkle with chopped mint.
Start to roll the spring roll like a burrito. Fold the wrapper over the filling, fold in 2 sides, and roll to seal. Take care when rolling as your wrapper can rip.
For the dipping sauce: Add the water to the nut butter in small amounts. You will need to slowly stir the water into the nut butter to incorporate. If you want your sauce thinner, add a little more water until you get your desired consistency.
