Option 1 for corn prep: Preheat your grill to medium-high heat. Then place the corn cobs directly on the grill and cook for 10-12 minutes (or until grill marks form) turning occasionally. Transfer the corn to a tray to cool then cut off the kernels.
Option 2 for corn prep: Bring a large pot of water to a boil on the stove. Once boiling, add your corn cobs. Then cover the pot and boil for 1-2 minutes. Transfer the corn to a tray to cool then cut off the kernels.
Add your cooked corn kernels, cotija cheese, red onion, and avocado to your Romaine in a medium bowl and toss with your desired amount of dressing.
Sprinkle crushed tortilla chips over the top and serve immediately.
