Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or aluminum foil for easy cleanup.

Slice 1 zucchini and 1 yellow squash into ¼-inch rounds. Halve about 1 cup of cherry tomatoes.

In a large mixing bowl, combine the sliced zucchini, yellow squash, and cherry tomatoes. Add 2-3 cloves of minced garlic, 2 tablespoons of olive oil, and ¼ cup of grated Parmesan cheese. Toss gently to coat the vegetables evenly.

Season with salt and pepper to taste. Toss the vegetables again to distribute the seasoning evenly.

Spread the seasoned vegetables in a single layer on the prepared baking sheet for even roasting.

Place the baking sheet in the preheated oven and roast for 20-25 minutes. Stir halfway through cooking to ensure even caramelization. The vegetables should be tender and slightly caramelized when done.

Remove from the oven and transfer to a serving dish. Garnish with freshly chopped basil or parsley for added freshness and color.
