If using Nutella - warm in the microwave for 15 to 30 seconds, or until it is very runny. Use a spoon to drizzle the Nutella over the yogurt, and sprinkle the almonds, ground flax, and cinnamon over top.
Top with the strawberries, kiwis, mangoes, blackberries and a drizzle of honey or a sprinkle of powdered sugar. Dig in!
