Preheat grill to medium-high. Slice zucchini lengthwise into strips. Core and quarter peppers. Toss zucchini and peppers with the melted Spreadables and half the balsamic vinegar. Place on the grill. Cook, turning as needed, for 7 to 10 minutes or until well-marked and tender. Cool to room temperature and chop into bite-sized pieces.

Toss chopped vegetables with cooked quinoa, onion, basil and parsley. Stir cottage cheese with lemon zest, lemon juice, garlic, salt, pepper, and remaining balsamic vinegar. Stir quinoa mixture with cottage cheese dressing until well combined. Sprinkle pine nuts over the salad (if using).
