Always dress the salad just before serving to prevent soggy greens. Watch nuts carefully while toasting to avoid burning, which can impart a bitter taste. Avoid aggressive tossing to prevent bruising delicate greens and crushing blueberries. For dairy-free, use vegan feta or omit. For nut-free, use toasted sunflower or pumpkin seeds. Consider adding fresh mint or basil, lemon or orange zest, grilled corn, roasted butternut squash, red pepper flakes, or homemade croutons for extra flavor. For a complete meal, add grilled chicken, pan-seared shrimp, or chickpeas.
