Make the Dressing:
In a glass jar with tight lid or measuring cup, combine tahini, white balsamic vinegar, and granulated garlic.
Whisk or shake vigorously until combined (it will look thick and separated at first).
Add water one tablespoon at a time, mixing between each addition, until dressing drizzles smoothly (usually 2-3 tablespoons total).
Season with salt and pepper to taste. The dressing should taste slightly overseasoned as it will coat mild ingredients. Set aside.
Build the Salad:
In your largest mixing bowl, add the spring mix or arugula as the base layer.
Add the cooled quinoa, spreading it evenly across the greens (ensure it's room temperature or chilled, never warm).
Arrange peach slices throughout the bowl, distributing them evenly.
Scatter cucumber half-moons, chopped almonds, basil, and mint across the surface.
Crumble goat cheese over everything in generous chunks.
Season with a small pinch of salt and a few grinds of black pepper.
Assemble and Serve:
Pour about three-quarters of the dressing over the salad.
Using clean hands or large salad servers, gently lift and fold everything together until thoroughly coated, being careful not to crush the peaches.
Taste and add more dressing or seasoning if needed.
Serve immediately for best texture and flavor.
