1. Make the peanut sauce by either combining all ingredients except water in a small blender/food processor, or stirring in a bowl with a spoon. If making it in a bowl, be sure to very finely grate your garlic and ginger. I used a microplane for this. Stir/blend in water, 1 tablespoon at a time, until desired consistency is reached. I like it a little thick as a filling, but thin it out more if using as a dip.
2. Assemble spring rolls: one at a time, dip the rice paper into water and let sit for 10+ seconds, or until very soft and flexible. Transfer to a plate or cutting board, and add your fillings to the lower third of the circle (see photos above). I used a spoonful of sauce, and 2-3 slices of each vegetable/herb, plus a sprinkle of sesame seeds in each roll.
3. To roll, first fold the left and right sides in, so they slightly cover the filling. Then, working from the side closest to you, roll the spring roll into a tight log. If you've made a burrito before, this is the same process. See photos above for visual.
4. Repeat the process for as many spring rolls as you'd like to make. For reference, this batch of sauce filled 6 rolls. Double or triple the recipe if you'd like to make more.
