There are so many ways to make a smoothie, but here is the way I like to do it: (serves 4)
This portion is for a big Vita-Mix container, so if you have a smaller blender, make 1/2 at a time.
1 c. water
1 c. juice (any kind is fine, we usually use OJ- with pulp) The pulp is very good for you.
1-2 big handful of spinach leaves (I buy the big package at Sam's or Costco. Once it starts to look wilted, just put it in the freezer and use it up until it's gone)
1-2 c. of any combination of frozen fruit (usually always strawberries and other fruits but I make sure it has blueberries because they are a wonderful Super Food)
1/2 c. yogurt (I prefer Greek yogurt-the honey vanilla flavor is so creamy & delicious)
2 T. ground flax seed or flax oil (good supply of plant Omega-3's, which the American diet is greatly lacking)
Optional: Add 1 scoop of protein powder (I prefer plant protein powders-especially hemp & rice)
Put the water, juice, & spinach in the blender first and blend until you don't see any more green leaves. Then add the rest of the ingredients into the blender in the order I've listed and blend until very smooth. If you want it thinner, add water. If you want it thicker, add ice or more frozen berries. If it's too sour, add a little agave, sugar, or sweet pineapple. You can also add cream of coconut to really sweeten it up. I would suggest making them a little sweeter at first so your kids get hooked on them, and then as their taste buds change, I would start to decrease the sugar. They'll never know :)
After I pour my kids smoothies, I leave the rest of the smoothie in the blender, add another handful of spinach, and blend it up to get in the extra nutrition for me! You can really add anything to your smoothies that you need to be eating more of. Experiment and have fun! Find your families' favorite! Almost 100% of any friends, kids, or family I have tried them on, love them!! I love hearing my friends tell me about how their kids love their smoothies every morning. It's music to my ears!! Enjoy!
