# Step-by-Step Directions:
01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper.

03 - Roast for 25-30 minutes, stirring once halfway through cooking, until vegetables are tender and lightly caramelized.
04 - While vegetables roast, whisk together olive oil, red wine vinegar, lemon juice, oregano, Dijon mustard, garlic, salt, and pepper in a small bowl until emulsified.
05 - Arrange cucumber slices on a large serving platter or in a salad bowl.
06 - Layer roasted vegetables over cucumber. Scatter Kalamata olives and feta cheese evenly across the top.
07 - Drizzle dressing over salad and garnish with chopped parsley. Toss gently and serve warm or at room temperature.
