Cheater smoothie

I like smoothies because they are a great way to sneak in healthy veggies that I don't eat very much. But sometimes smoothies can be some work getting the fruit out and cutting it up. So on some days I use prepared smoothie bags an add some greens. I only buy the smoothies that are just fruit because i dont like the added sweeteners or yogurt. i can easily add my own greek yogurt or kefir. I like it because I already know that the fruit in the smoothie is going to taste good together. The kids like them way better than my own concoctions. They like em so much that I usually only get a sip before someone takes over my glass.
Here is my list of add-ins.
2 Tb very green powder
1/2 C plain Greek yogurt
1/2 c kefir
1 handful kale leaves
1 handful spinach leaves
1Tb ground flax seeds.

I don't use all of the add-ins. I usually add the green powder, either yogurt or kefir, and either spinach or kale depending on what I have.
