Blend the almond butter, water, dates and vanilla extract in a blender. Then add oats and chia seed and blend again until well combined. Place the Greek yogurt in a small bowl and stir in some of the cherry juice from the thawed cherries. You can sweeten this up with some stevia or honey at this point, if you'd like. Layer the yogurt and the oatmeal mixture in a bowl and top with cherries.
