Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Toss zucchini, yellow squash, red bell pepper, and red onion with 2 tbsp olive oil, 1/4 tsp salt, and 1/8 tsp black pepper in a large bowl until evenly coated.
  2. Step 2: Spread vegetables in a single layer on a parchment-lined baking sheet. Roast for 20-25 minutes, flipping halfway through, until vegetables are tender and slightly caramelized at the edges.
  3. Step 3: While vegetables roast, whisk together 1 tbsp olive oil, 1 tbsp red wine vinegar, 1 tsp dijon mustard, 1/2 tsp honey, 1/4 tsp salt, 1/8 tsp black pepper, and minced basil in a small bowl.
  4. Step 4: Remove vegetables from oven and transfer to a serving dish. Drizzle with the vinaigrette, then sprinkle with remaining 1 tbsp minced basil and 1 tbsp minced parsley.
  5. Step 5: Serve warm or at room temperature, ensuring each bite has a mix of roasted vegetables and fresh herbs.
