I've used hemp seeds and avocado a lot - I consider them staples for substantial smoothies. Wouldn't use green tea as I find it too stimulating, and water serves me fine. Cold-pressed coconut oil, raw cacao butter, bee pollen...all good for sustained energy. I generally do not care for nuts and other seeds in my LGSs, though I have started making nut 'milkshakes" LGSs and enjoying them warm. Check out my website for lots of recipe ideas, and for a refresher on proportions, so you don't end up with pond sludge.
