cold milk of magnesia.......hmmmm, so they DID improve the taste (but not by much I see.)
Seriously though, that stuff was pretty bad. When I'm in a pinch, I just toss the greens with a tablespoon or so of olive oil (or a neutral tasting oil), then squirt a lemon wedge on top, a pinch of salt and a good grating of black pepper. Then toss.
