I tried this smoothie with Greek yogurt rather than protein powder and it had been incredibly spinachy so I’d propose working with just one cup spinach if making use of yogurt as the protein. For those who insert nuts or seeds, I like to recommend adding about 2 Tablespoons total. https://lanehbvha.suomiblog.com/the-best-side-of-vegan-protein-powders-42134904
