In a liquid measuring cup or small bowl combine chia seeds with water, whisk together & let stand for about 20 minutes. (Makes about 1 1/8 cups chia gel.)
Place the chia gel, frozen berries, cardamom, almond milk, maple syrup, vanilla, avocado & lime juice in a blender. Cover & blend on high until thick & creamy.
Pour into 2 glasses. Garnish with additional berries (I used frozen goji berries) and a lime wedge. Serve immediately.
