Pretty good! I made a few substitutions based on what I had available. I used plain whole-fat yogurt instead of nonfat Greek, 1/4 cup pineapple chunks (not frozen), and 2-3 tbsp hulled hemp seeds instead of chia. I eyeballed the spinach w a couple handfuls, so probably more than a cup. I also forgot to add any maple syrup or honey, though I meant to. It turned out pretty yummy, even with less pineapple than recommended and no sweeteners and more spinach (and hemp) than recommended. It wasn't too thick, and mostly tasted of banana with no spinach taste. My 8mo baby demanded a taste, and ate a few baby spoonfuls himself. Just the sliced up banana being frozen was enough to make the smoothie really cold, even though my pineapple was just refrigerated. Very quick and surprisingly filling.
