Marinate the Steak: In a bowl, combine the steak with 3 tablespoons olive oil, 3 tablespoons balsamic vinegar, and 1 teaspoon garlic powder. Marinate for at least 30 minutes (or up to 2 hours) in the refrigerator.
Grill the Steak: Heat a grill to medium-high heat. Grill the steak for 5-7 minutes per side, or until it reaches your desired level of doneness. Let it rest for 5 minutes before slicing thinly.
Option to grill or char the corn: Grill corn on the cob until the corn is charred. Cut corn off the cob and set aside. OR add corn kernals to a cast iron pan. Cook on high heat until kernals are charred.
Prepare the Salad: In a large bowl, combine the chopped lettuce, corn, and tomato.
Make the Dressing: In a separate small bowl, whisk together 3 tablespoons olive oil, 3 tablespoons balsamic vinegar, 1 teaspoon garlic powder, and the juice of 1 lemon. Season with salt and pepper to taste.
Assemble and Serve: Add the sliced steak to the salad. Pour the dressing over the salad and toss to coat. Crumble the Gorgonzola cheese on top. Serve immediately.
