Cut all vegetables (and fruit, if any) in match stick-size strips. Put them in front of you on a large cutting board sorted by color.
Wash the fresh herbs and/or lettuce. Take off the leaves of the herb twigs and detach enough lettuce leaves. Then I put the leaves in separate piles next to the veggie sticks on the cutting board.
Soak brown rice (vermicelli) noodles in hot water for about 5 minutes and rinse in cold water (as per the instructions on the noodle package). Transfer them to a bowl and place it next to your cutting board.
Before starting to roll the spring rolls, set everything out in front of you; you want everything within arm-reach to quickly wrap the rice paper after it is soaked. Right next to the cutting board put a large bowl with some water in it (to soak the rice paper in).
Slide a sheet of rice paper in the water and leave it in there for 30-60 seconds or until the rice paper has softened enough (make sure not to leave it in the water too long otherwise the rice paper will break and fall apart).
Once softened transfer the rice paper, using both hands with spread out fingers, to the cutting board. You can moisten the cutting board by wiping a wet hand over it before transferring the soaked rice paper to it. This is to prevent the rice paper to stick to the cutting board.
Working quite quick, arrange veggies and noodles in the middle of the soaked rice paper, making sure all the veggie sticks point the same way. Top it with mint and/or coriander, lettuce (optional), sesame seeds and/or peanuts.
Gently fold the left and right side of the rice paper over the filling (see picture in the text above), followed by folding over the bottom side (see above). Now roll up the rice paper from bottom to top (see picture in the text above).
Serve with peanut sauce and soy-ginger dipping sauce on the side.
