There are many green smoothie recipes available in books and online.  The idea of using fresh green stuff in a quick breakfast smoothie is appealing but spinach is very high is oxalates and kale in its raw form is a problem for the thyroid.  Most of the recipes I’ve seen use either one or the other; the cruciferous vegetables (kale, etc.) are best cooked or fermented while high oxalate foods (spinach, beets and beet greens, swiss chard) are best limited in the diet and should not be eaten on a daily basis. These recipes also often use nut butter or nut milks so I thought I’d offer something different.  Leave out the egg yolks if you wish but know that they are a superfood when the eggs come from truly healthy chickens. Let me know what you think!

Serves 1

1/2 avocado

1/2 banana

1 cup packed endive, escarole or mixed leaf lettuce

2 Tbsp. collagen powder (Great Lakes)

2 egg yolks (use fresh eggs from pasture-raised chickens only, and save the whites for baking–use 2 egg whites in place of 1 egg)

1/4 cup water

stevia and vanilla to taste, optional

Place all ingredients except egg yolks in blender.  Blend very well.  Add egg yolks and blend briefly until just homogenous.
