Prepare the Fruit: If using a fresh peach, wash and slice it into large chunks. If using frozen peaches, no preparation is needed.
Combine Ingredients: In a blender, add the frozen banana, peach chunks, Greek yogurt, and ice (if using).
Blend Until Smooth: Blend the mixture on high until smooth and creamy. If necessary, stop the blender and scrape down the sides to ensure everything is well combined.
Adjust Consistency: If the smoothie is too thick, you can add a splash of water or milk to help it blend more easily.
Taste and Sweeten (Optional): Taste the smoothie and add a drizzle of honey or maple syrup if you prefer it sweeter.
Serve: Pour the smoothie into a glass and enjoy immediately.
Garnish (Optional): For an extra touch, you can garnish with a slice of peach or a sprinkle of granola on top.
