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 olive oil and the juice from lemon over the zucchini. Add Italian seasoning, salt, and 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 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.
