Bring a pot of water to a boil. Into a large bowl, grate the corn on the large holes of a box grater. You can add the cobs to the boiling water along with the noodles to infuse more corn flavor, if you’d like. Cook the noodles according to the package instructions. When there are 2 minutes remaining, place the greens on top and gently submerge them into the water.
Use tongs to remove the corn (if using) and transfer the greens from the pot onto your cutting board. Drain and rinse the noodles with cold water until the noodles are just lukewarm. Once the greens are cool enough to handle, squeeze out any excess water, then thinly slice it.
In the bowl with the corn, add the sesame oil, tahini, vinegar, miso, ginger, and salt. Whisk until combined. You can use a fork to help mash/mix the miso in. Add the noodles/greens to the bowl and toss to coat.
Serve the noodles topped with chicken, cucumber, avocado, herbs, sesame seeds, and a squeeze of lime.
