Heat your grill pan over medium-high heat, then add the corn on the cob and cook for about 12-15 minutes, making sure to turn to evenly cook all sides. Remove from the grill and let cool. Once cool, cut the kernels from the ears of corn with a knife; let cool.
Chop your chicken, lettuce, veggies, and cheese.
Place the chopped romaine and mixed greens in a large salad bowl.
Add the cooled grilled corn, tomatoes, bell pepper, garbanzo beans, avocado, and extra sharp cheddar to the top.
Drizzle with the well-whisked vinaigrette or creamy buttermilk ranch dressing and toss to coat evenly. Serve immediately. Enjoy.
