Combine the spinach, banana, almond butter, 1 cup of the frozen fruit, and chia seeds (if using) in a blender. Pour in the almond milk and start blending. If too thick, add more almond milk until smooth.
Add the ice and blend once more to chill the smoothie.
Taste and decide if you'd like it sweeter. If so, add more of the frozen fruit and blend again. Adjust the thickness by adding almond milk. DEVOUR!
