Instructions

1. Step 1: Heat 2 tbsp olive oil in a large nonstick skillet over medium-high heat. Add 2 medium zucchini sliced into 1/4-inch rounds and 1 thinly sliced medium red onion. Sauté for 6-7 minutes, stirring occasionally, until zucchini is golden at edges and onions are translucent and caramelized.

3. Step 3: Transfer the warm zucchini and onion mixture to a large bowl. Pour the parsley vinaigrette over the vegetables and toss gently to coat evenly.
4. Step 4: Sprinkle 2 tbsp toasted pine nuts on top for crunch if desired. Serve the salad warm or at room temperature.
