Place the vermicelli noodles in a bowl and cover with lukewarm water for 2 minutes, then drain (or follow package directions).
Peel the shrimp, cut them in half lengthwise and devein them.then Remove the crunchy core from the lettuce leaves.
Tip - LETTUCE PACKAGE (Note 4): Place vermicelli noodles and bean sprouts in a lettuce leaf, then roll it up, seam side down. Repeat.
Fill a large bowl with lukewarm water. The bowl does not need to be large enough to hold the entire rice paper at one time.
Place two sheets of rice together (if using 2). Note which side is the smooth side - this is supposed to be the outside of the spring roll. Immerse the rice leaves in water (both at the same time, together) for 2 seconds. If your bowl isn't big enough to hold the entire rice paper at one time that's fine, just rotate it and count 2 seconds for each section you dip in the water.
Place the two sheets of rice (one on top of the other, they will stick together) on a board or counter with the smooth side down.THEN On the top of the rice paper, place 3 shrimp with a mint leaf in between, as in the photo below.
Place the lettuce package, seam side down, in the middle of the rice paper, fold the left and right edges of the rice paper together, then starting at the bottom, roll up to cover the lettuce package. Then continue to roll firmly. The rice paper is sticky, it will seal.
If you have placed the ingredients on the rice paper like in the photo below, your rice paper rolls should look pretty with the shrimp and mint leaves on the smooth side of the roll and the seam on the side or bottom. below the roll.
Serve immediately with the peanut dip.
