dragnlaw, you can dry it, or blanch and freeze it, or can it.
Here is a list of greens that have the good quality of producing nitric oxide in the body.
Kale, spinach, Swiss chard, arugula, beet greens, beets, bok choy, collard greens, mustard greens, turnip greens, napa cabbage, Brussels sprouts, broccoli, cauliflower, cilantro, parsley and asparagus. You can avoid the high oxalates by avoiding spinach, beets and beet greens, swiss chard, and dandelion leaves.
I eat greens everyday. Lately 8-10 oz of spinach/collard greens/turnip greens, after my orange, before my breakfast.
I checked pepperhead's flicker photo account, and he is posting pictures there. I hope he is not sick.
