Preheat the grill to medium-high heat. Season the flank steak with salt and black pepper, then drizzle with 1 tablespoon of olive oil.
Grill the steak for about 5-7 minutes on each side, or until it reaches your desired level of doneness. Remove from the grill and let it rest for 10 minutes before slicing thinly against the grain.
While the steak is resting, grill the corn for about 10-12 minutes, turning occasionally until charred. If using frozen corn, sauté it in a skillet over medium heat until heated through and slightly browned.
In a large bowl, combine the mixed salad greens, cherry tomatoes, grilled corn, and crumbled Gorgonzola cheese.
In a small bowl, whisk together the balsamic vinegar, honey, Dijon mustard, and remaining olive oil until well combined.
Drizzle the dressing over the salad and toss gently to combine. Top with the sliced steak.
Serve immediately, garnished with additional Gorgonzola if desired.
