This is a great time to tap into an easy-to-find option: baby food.
You can buy it in jars, but with advent of the pouch adding a pure fruit or a mixed fruit & veggie puree to your drink is super simple (some even have chia!).
Most brands now offer some of their foods in a pouch (even Target has several options) and there are also plenty of organic choices.
One of the organic options that I have found to be priced reasonably as well as having a lot of good combinations is Happy Baby, which is included below in my “Won’t You Be My Baby” smoothie recipe:
1 well-packed cup of chard
1 pouch Happy Baby banana, beet, blueberry
4 medium-sized whole, frozen strawberries
1 tsp chia seeds
1/4 water (optional and add as much or as little as you want)
The color of this smoothie depends on how much greens you add it typically is more beet colored than green.
