This was "clean out my fridge" day. I didn't measure anything because I was using up whatever I had, but I list suggested amounts in case you want some guidance.
Ingredients:
a bunch of kale and any other greens you like to cook
1/2-1 onion, chopped
1/2-1 lb mushrooms, chopped (optional)
2-4 cloves garlic, chopped (to taste)
1/2-1 oz pecans or walnuts, chopped (optional)
1 Tbsp spicy pecan vinegar (or other flavored vinegar, or lime/lemon/orange juice)
Steam the greens, onion, garlic and mushroom for 10-20 minutes on stove, or 2-3 minutes in pressure cooker. Add the rest, toss and serve. Yummy.
