Organic frozen peaches and raspberries will give you the best flavor and color.
Place raspberries, peach slices, yogurt, zucchini, flaxseed, honey, vanilla, and salt in a blender; process until smooth, 20 to 30 seconds, stopping to stir and scrape down sides as needed. (If mixture is too thick, add up to 4 tablespoons water and process again.) Divide between 2 bowls and sprinkle with toppings. Serve immediately.
