Instructions

  1. Step 1: Preheat your oven to 425°F. In a large bowl, combine 1 medium zucchini sliced into 1/2-inch rounds, 1 large red bell pepper cut into 1-inch pieces, 1 small eggplant diced into 1/2-inch cubes, and 1 medium yellow squash sliced into 1/2-inch rounds.
  2. Step 2: In a small bowl, whisk together 4 tbsp extra virgin olive oil, 1 tsp finely chopped fresh rosemary, 1 tsp finely chopped fresh thyme, and 3 minced garlic cloves until well combined and fragrant.
  3. Step 3: Pour the herb-infused olive oil over the mixed vegetables, sprinkle with 1 tsp sea salt and 1/2 tsp freshly ground black pepper, then toss thoroughly to ensure every piece is evenly coated.
  4. Step 4: Spread the vegetables in a single layer on a large rimmed baking sheet and roast in the preheated oven for 20 minutes, stirring halfway through, until the edges are golden and tender but not mushy.
