In a blender, add in the yogurt, strawberries, bananas, and raspberries. If you want a thicker smoothie, add in frozen strawberries instead of fresh ones.
Blend until everything is smooth and well blended. You may have to give it a stir to help get things moving.
Pour the smoothie into a bowl.
Top the smoothie with the crushed breakfast flat, bananas, strawberries, and raspberries. Eat up!
