Kale and Onion Stirfry

I got this recipe attached to a bunch of kale and modified it for my own ends. I think Kale is an acquired taste, but dark green leafy vegetables are very important for health and kale has more fibre than you can shake a stick at.

1 pound fresh green kale
2 onions, sliced
(2 cups of sliced or quartered musrooms, optional)
2 tbsp. rice vinegar
2 tbsp. light soy sauce
1/2 tsp. sweetener

Clean Kale and remove ribs. (I find that the best way to do this quickly is to hold the end of the stalk and pull your fingers down the stalk peeling off the leafy part.) Spray wok or skillet with cooking spray. Heat on high, add kale and onions (and optional mushrooms. (I usually put in the onions (and mushrooms) first and the kale second) Stir for 1 to 2 minutes. Pour in rice vinegar, lite soy sauce and sweetener. Reduce to medium heat and stir until kale and onions are tender-crisp. Makes 4 servings.
