I loved the ease of these smoothies and the taste of all of them

I did a smoothie each day and loved the taste and ease of making them. Making them each day made it easier for me to reach for a healthier snack in the afternoon as well, wasn’t craving anything that wasn’t good for me. I did add spinach each day as well as the chia seeds and collagen.

Fun challenge.

This was a great challenge. I appreciate receiving a graceful list to prepare. I love making smoothies and always want to try to flavors and combinations. Getting help to create new drinks is great.

The power cherry smoothie was fantastic. A new one for my arsenal.

Summer smoothie challenge

I enjoyed this challenge at the start of summer! Getting the list of ingredients for the whole challenge was very helpful for planning. I’ll be making several of them again!

Free, fun, and easy!

Jen always makes great recipes that are easy to follow and plans that are easy to implement! Want to try making better food choices? Wondering how smoothies that often contain vegetables can be good? Want to move toward more whole food plant-based eating but are not sure how to start? Jen’s your girl! This 5-day challenge is an incredibly easy way to dip your toes in the water with someone encouraging you and holding your hand through each step.

Always something new to try

I started my daily smoothie routine when Jen published her first book many years ago. After all of these years it is exciting to still have new ones to try. The Best Green Smoothie is a favorite of mine. I seldom buy watermelon, so the Watermelon Smoothie was a super fun and delicious new recipe that I will continue to make. Thanks Jen.

Great way to try new flavors

This was a fun, healthy challenge that I would do again! There were combinations I wouldn’t have thought about doing before. There were some familiar flavor profiles as well. I appreciated the shopping list ahead of time so I knew what I needed and didn’t have to run out that morning or the night before.

Learned great ways to vary my smoothie routine!

I am a huge smoothie and smoothie bowl person – I make smoothies or bowls almost everyday using my vitamix! I’m also vegetarian and love plant based eating! I joined to challenge to learn more about great and easy smoothie making and to add variety to the smoothies and bowls I make. The challenge added great and yummy variety to my routine. It also motivated me to make more and stick to my healthy eating goals. The freeze ahead ideas are great too! Really enjoyed the challenge!!

Fun!

I got to try pomegranate juice and took a leap of faith with added cauliflower to my smoothies. I’ll definitely use cauliflower in future blends.

I loved it!

The Summer Smoothie Challenge was incredible! I honestly can’t believe it was free. I first discovered it through Vitamix and thought it would be a great way to get more use out of my blender. I’m so glad I joined. My biggest surprise was the Strawberry Protein Shake—I never imagined I’d actually look forward to drinking a protein shake! Jen makes healthy eating feel fresh, fun, and delicious while teaching nutrition in a way that really makes sense for women like me. I can’t thank the Simple Green Smoothies team enough!
