Soak the dried rice vermicelli noodles in warm water until they're soft. Drain and set aside.
In a small bowl, mix the minced garlic, sugar, and tamari (or soy sauce) to create a marinade for the tofu. Coat the tofu strips evenly with the marinade and set aside.
Prepare the vegetables: shred the lettuce, and chop the fresh mint, Thai basil, and chives. Thinly slice the bird's eye chilies. Rinse the bean sprouts under cold running water and let them dry in a colander. Chop up your Vietnamese coriander leaves if you are uisng them. Mix all the herbs and veggies together along with the salt.
For the dipping sauce, combine the thinly sliced bird’s eye chilies, grated ginger, minced garlic, hoisin sauce, peanut butter, and water in a bowl. Using the tines of a fork, mix well until smooth.
Fill a large bowl with warm water. Working with 2-3 pieces of rice paper, dip each rice paper wrapper in the water for a few seconds. Place the wet rice papers on a clean work surface spread out so each one doesn't stick to the others.
Place a small amount of the soaked rice vermicelli noodles, marinated tofu, and mixed herbs on each softened rice paper.
Carefully roll the rice paper over the filling, tucking in the sides to enclose the ingredients tightly. Repeat with the remaining ingredients and rice paper wrappers.
Serve the goi cuon with the prepared dipping sauce and garnish with fresh mint leaves, Thai basil, sliced chives, bird’s eye chilies, and toasted sesame seeds.
