Creamy Kale Sauce

You wouldn't think that cream sauce could be low fat and still taste
good, did you? This following recipe has, to my knowledge, between
2-4 grams of fat per serving (my pasta has 2 grams of fat per serving,
and the soymilk has 2 grams as well), even if you have a really BIG
plate. I tend to use more sauce than my husband, so your mileage may
vary in serving sizes. One important note: Do NOT substitute low-fat
or lite soymilks for the regular soymilk. There is a definite lack of
taste compared to regular soymilks, and it's just not the same.
This is adapted from a recipe from Simply Vegan (Barbara's Kale Sauce):
Ingredients:
2 cups plain Edensoy soymilk (do not substitute)
1/3-1/2 cup nutritional yeast
1/2 tsp each: dill, thyme, basil
1 tsp garlic powder
1/2 tsp salt
1/2 tsp pepper (opt)
3 tsp flour (whole wheat only - do not use unbleached white)
4 medium/large leaves of kale
