Use an immersion blender to blend together (or whisk) 1/4 cup water, 1/4 cup tahini, 1/4 cup canola oil, 2 Tablespoons rice vinegar, 2 Tablespoons grated ginger, 2 Tablespoons miso paste, 2 cloves garlic, 1 teaspoon granulated sugar, 1 teaspoon kosher salt, and 1 teaspoon chili garlic sauce in a small bowl or 2-cup measuring cup. Set aside.
Noodle Salad
Bring a small pot of water to a boil. Add 2 cups shelled edamame and cook for 2-3 minutes. Scoop the edamame out with a slotted spoon or drain in a small colander and rinse with cold water until the edamame is cool. Set aside.
Bring more water to a boil (or re-use the edamame water) and add 8 ounces dried ramen or other noodles. Cook for 2-3 minutes until the noodles are softened and separated. Drain the noodles and rinse with cold water until cool
Add the drained noodles to a large bowl. Add about 1/2 cup of the sesame dressing and toss the noodles to coat. Add 2 cups lightly packed shredded napa cabbage, the drained edamame, the juliened cucumber, the juliened carrots, and the sliced celery. Toss to coat, and assess how much more dressing you want to add. Add about half of what is left for lightly dressed salad, or up to all of it for very saucy salad. Sprinkle with sliced green onions, or minced cilantro or chives, if desired.
Make-Ahead Instructions
Note that the dressing can be made up to 2 days in advance, and in fact this helps to improve its flavor. Store it in an airtight container in the fridge.
You can also make the salad up to one day ahead of time (complete the entire recipe) and store the salad in a covered bowl or an airtight container in the fridge. In this case, I recommend not adding all of the dressing - reserve some and add it if needed just before serving.
Notes
Instead of ramen, you can use any other quick-cooking noodles (follow the directions on the package to cook). Use rice noodles or another type of gluten-free ramen or noodles to make this salad gluten-free.
