01 - Set oven to 400°F and line a baking sheet with parchment paper.
02 - In a large bowl, toss carrot sticks and sliced red onion with 1 tablespoon olive oil, a pinch of salt, and pepper. Spread evenly on the prepared baking sheet.
03 - Place baking sheet in oven and roast for 25 to 30 minutes, turning vegetables halfway through, until carrots are tender and caramelized at the edges. Set aside to cool slightly.
04 - In a small bowl, whisk together the remaining olive oil, honey, lemon juice, Dijon mustard, minced garlic, salt, and pepper until emulsified.
05 - Combine mixed salad greens, roasted carrots and onions, half of the crumbled feta, half of the pumpkin seeds, and most of the chopped parsley and mint in a large bowl. Pour the dressing over and toss gently to evenly coat.
06 - Transfer mixture to a serving platter or individual plates. Garnish with remaining feta, pumpkin seeds, and herbs. Serve immediately.
