Trim and coarsely shred zucchini into a sieve over a large bowl. Toss with 1 teaspoon salt and allow to sit for 10 minutes. Transfer to a clean kitchen towel and squeeze out as much moisture as possible.
In another bowl, whisk together the egg, green onions, and pepper. Stir the zucchini and flour into the egg mixture.
Heat the oil in a large pan (preferably cast iron) and drop 6 mounds of the mixture into the pan. Lightly flatten and cook for 5-7 minutes turning half way through, until golden brown on each side.
Salad Preparation
Heat the grill to medium high, brush the corn, green onions and the jalapeño pepper with oil and grill until slightly charred.
Whisk together all the dressing ingredients, add the chopped jalapeño. Toss the lettuce in some of the dressing, arrange the corn you've cut off the cob, chopped green onion, tomatoes, and avocado on top. Drizzle with the remaining dressing. Serve with fritters.
