Preheat the grill over medium high heat (approximately 400 degrees Fahrenheit).
Trim the ends off 3 medium zucchinis and cut each zucchini into quarters lengthwise.
Place the zucchini in a large mixing bowl.
Drizzle 1 tablespoon olive oil and the juice from ½ lemon over the zucchini. Add 1 teaspoon Italian seasoning, ½ teaspoon salt, and ½ teaspoon black pepper. Gently toss until the zucchini is evenly coated.
Place the zucchini spears directly on the grill over direct heat. Cook for 4-5 minutes until the zucchini is slightly charred. Flip and grill for 3-4 more minutes on the opposite side until the zucchini is tender.
Remove from the grill and place on a serving plate.
Sprinkle ½ cup grated Parmesan cheese evenly over the zucchini.
Let the zucchinis sit for a few minutes for the cheese to melt slightly and then the zucchini is ready to serve and enjoy!
Notes
Refrigerate the leftovers in an airtight container for up to 5 days. We recommend freshly grated Parmesan Cheese for this recipe.
