01 - Wash berries thoroughly and pat dry gently with paper towels. Hull and slice strawberries into quarters or bite-sized pieces if using. Leave blueberries and raspberries whole.
02 - Spoon 2 to 3 tablespoons of Greek yogurt into the bottom of each of four clear glasses or jars, creating an even base layer.
03 - Drizzle approximately 1/2 teaspoon of honey or maple syrup evenly over the yogurt layer in each glass.
04 - Distribute a small handful of mixed berries across the yogurt layer, arranging them against the glass walls for visual appeal.
05 - Sprinkle 2 to 3 tablespoons of granola over the berry layer, ensuring even coverage while maintaining visibility of the fruit.
06 - Continue alternating layers of yogurt, sweetener, berries, and granola until glasses are filled to within 1/2 inch of the rim, typically creating 2 to 3 complete layers.
07 - Top each parfait with remaining granola, chopped nuts, chia seeds, and fresh lemon zest if using. Garnish with a few whole berries for presentation.
08 - Serve immediately to maintain granola crunch, or refrigerate for 15 to 30 minutes for softer textures. Parfaits can be assembled up to 4 hours ahead if stored covered in the refrigerator.
