I got this recipe from Mark on the Fuhrman forums (modified a bit).Ingredients for 2 large (main dish) servings:
1 bunch kale and/or collard greens
1 leek or part of an onion (optional)
1 large sweet potato
1 small lime, juiced or 1/2 large
1/3 cup cashews
Destem the greens, chop and cook in a small amount of water, along with the chopped leek. Cook for 15-20 minutes for kale, about 30 minutes for collard greens.
peel the sweet potato, chop and steam for 15-20 minutes.
Blend the sweet potato, cashews, lime and 1/2 cup water. Add more water if needed.
Pour the sauce over the greens (which have some water in them) and stir.
This makes a little too much sauce, but I find it's hard to blend smaller quantities in the blender. So you could add less sauce and save the rest for tomorrow and have another batch then. Or if you are serving more than 2 people, cook up 2 bunches of the greens.
