This is my go-to smoothie. On days where I'm short on time, I'll often throw the ingredients in my magic bullet and take it to-go. It's super customizable, too. You can add or subtract flavors, or substitute similar ingredients. I like to make mine with unsweetened, unflavored kefir. Check out my version below.
1 frozen sliced banana
1 tablespoon all-natural peanut butter (just peanuts and salt)
1-1/2 cup unflavored kefir (adjust to achieve desired consistency)
1 tablespoon honey
a handful of baby spinach
Blend all ingredients until smooth.
Makes 1 serving
