CORN: Peel and clean the corn. Preheat an indoor or outdoor grill to medium-high heat. Clean the grill grates then grill the corn for 6-10 minutes or until lightly blistered and charred on all sides. Remove to a cutting board. When cool enough to handle shave the corn off the cob and set it aside.
DRESSING: Toss the oil, lime juice, honey, chopped serrano, cilantro, and salt and pepper in a mason jar.
SALAD: Add the lettuce, shaved corn, and pickled onions to a large dish. Toss with ¾ of the dressing, taste, and add more as desired. Serve with sliced avocados on top and crumbled Cotija cheese.
