Ingredients
  

2 cups cherry tomatoes, halved

1 medium zucchini, diced

1 bell pepper (red or yellow), chopped

1 cup corn kernels (fresh or frozen)

1 medium onion, diced

3 cloves garlic, minced

1 teaspoon dried oregano

1 teaspoon dried basil

½ teaspoon red pepper flakes (optional)

Salt and pepper, to taste

1 cup shredded mozzarella cheese

½ cup grated Parmesan cheese

2 tablespoons olive oil

Fresh basil leaves, for garnish

Instructions
 

Preheat the Oven: Preheat your oven to 375°F (190°C).

    Prepare the Pan: In a large oven-safe skillet or casserole dish, heat the olive oil over medium heat. Add the diced onion and sauté until translucent, about 3-4 minutes.

      Add the Garlic: Stir in the minced garlic and cook for an additional 1 minute until fragrant.

        Mix in the Vegetables: Add the chopped bell pepper, zucchini, cherry tomatoes, and corn to the skillet. Stir well to combine.

          Season: Sprinkle in the dried oregano, dried basil, red pepper flakes (if using), salt, and pepper. Mix thoroughly to ensure all vegetables are well-seasoned.

            Layer the Cheese: Evenly sprinkle the shredded mozzarella cheese and grated Parmesan on top of the vegetable mixture.

              Bake: Transfer the skillet or casserole dish to the preheated oven and bake for about 25-30 minutes, or until the cheese is bubbly and golden brown, and the vegetables are tender.

                Garnish and Serve: Remove from the oven, let it cool for a few minutes, and garnish with fresh basil leaves before serving.
