Preheat the oven to 200 degrees and let it heat up. Dice the zucchini and eggplant into dice the size of a die, and cut the cherry tomatoes in half. Spread the chopped vegetables on a baking tray lined with parchment paper; drizzle olive oil, salt, and black pepper over them and mix well. Bake the vegetables for approximately
20-25 minutes until they soften and lightly brown.
