Chop the scallion through most of the greens. Combine with the cilantro, lime zest, and salt on a cutting board and chop until everything is well-combined and minced fairly fine (as if you were making a gremolata).
Remove the kernels from the corn cobs and toss with the cilantro-scallion mixture and olive oil. To the sweet corn mixture add the arugula, cooked couscous, pickled sweet peppers, feta, and toasted pepitas.
Prepare the dressing as stated and drizzle a few tablespoons over the salad. Toss, adding more dressing as needed, until the salad is combined and well coated with dressing.
