Avocado Berry Smoothie Ingredients

To get my little guy eating some good veggies and a balanced diet, I sometimes trick him into eating some of his least favorite (and most nutritious) enemies: kale, peas, spinach, avocado, to name a few.

And you know what? I’m a proud hider of vegetables, and if you want proof, check out the secret ingredient some of my other recipes.

Most importantly, a smoothie like this keeps him happy and makes me feel good, too! This Avocado Berry Smoothie took just 4 minutes to make, and it was big enough for the two of us to share.

All it takes to make this smoothie is mixed fruit, oats, collagen, cauliflower, and avocado. The ingredients are all pretty simple, but they all serve a purpose.

Avocado in Smoothies

If you aren’t already putting avocados in your smoothie, you really should start. Not only is adding avocado an awesome way to get healthy fat into your diet (and you need fat!), but it makes the smoothie super creamy and dreamy. 

Cauliflower in Smoothies

If there’s one or two veggies that don’t really suit me (ex: green peppers), I move on and find a different option that I like. But if there’s a picky eater in the house, and there’s at least one in mine, creativity is very important.

Adding a little cauliflower to your smoothie is a super simple way to get a little extra good stuff. There is zero cauliflower taste when you mix it with all the fruit and grains, so you don’t even notice it’s in there!

Mixed Fruit in Smoothies

Fruit is an awesome source of fiber and vitamins. Of course, fruit contains sugar, but I firmly believe that natural, unprocessed sugar is not the enemy. That said, everything should be in moderation.

This is a smoothie, after all, and I want it to taste good, so yes, there’s some fruit in here, but not a ton. And maybe most importantly, it’s balanced out with a respectable amount of protein, fat, and grains.

There won’t be a sugar crash after you have this!

Adding Collagen to Smoothies

Adding grass-fed collagen to your smoothie is a great way to get some extra protein in, and here I used use Vital Proteins (affiliate link).

I bought it at Walmart (see my full list of other healthy Walmart groceries)! But I also really like Paleo Valley brand. Always choose a reputable, reliable source for your collagen!

If you’re looking for other ways to get your collagen in, my Collagen Kombucha Mocktail recipe is one of the most delicious ways to incorporate collagen into your diet! And be sure to check out my recipe for Collagen-infused Chili Potato Skins recipe (it’s Whole30!) over on the Vital Proteins blog.

The really nice thing about smoothies is that you can pretty much add whatever you’ve got laying around, plus you can design it to meet your dietary restrictions.

This avocado and mixed fruit smoothie has everything that I’m looking for, but here are some ideas to help meet your specific needs:

Mixed Fruit Smoothie Variations

  • For a vegetarian smoothie: Omit the collagen.
  • For a lower carb or lower sugar diet smoothie: Omit the peaches and banana, then substitute extra mixed blueberries and raspberries.
  • Substitute any type of milk you prefer: Coconut, Oat, or regular cow’s milk would all work great!
  • For grain-free / Paleo smoothie: Omit the oats.

If you happen to be curious about the blender I have, it’s from Blendtec (affiliate link). And I’m obsessed with it. I love it. I’ve had it for about four years or so, and it’s a total workhorse. My one word of advice, though, is to get the twister jar with it. Because if you like to cook, you’ll definitely use it.
