Buttery toasted pine nuts, salty Pecorino Romano, and fragrant basil add intrigue to this simple summer side dish.
Generously sprinkle zucchini and squash slices with salt; let stand in a colander 30 minutes. Rinse and pat dry, then transfer to a large bowl. Whisk together oil, lemon juice, Dijon, and honey. Drizzle mixture over slices. Add pine nuts, cheese, and basil; toss to coat. Season with salt and pepper. Serve immediately, or let stand at room temperature up to 2 hours.
