Protein shake add-in question.

CanToGirl

I am loving protein shakes with fruit! But really want to add some greens and other beneficial ingredients such as kale, advacado and spinach. But really worried it's going to change the taste of the shake. I like my shakes sweet tasting.
So how much difference can you tell the taste of your shake? And if you have any good recipe including greens, please share. I would really appreciate it!!

Start with a little less than a cup of spinach and see how that tastes. Double the amount of spinach the next time and see how it tastes. I put Romaine Lettuce in mine. It has no taste but still provides protein.

Buy a juicer for the greens and veggies. Google fit juice.
