This smoothie is the morning go-to for our blog editor, who likes starting her day with good hydration, protein, and fiber. She likes a thinner smoothie because it's easier to suck through a straw when she's got to drink it on the road. If you prefer a thick smoothie, start with less water and thin to your preferred consistency.
2 cups baby spinach
2 Tbsp. plain, non-fat Greek yogurt
1 Tbsp. peanut butter
1 small, very ripe banana, frozen and sliced
2 Tbsp. oatmeal
1 cup water
