Buckwheat might work for you too. Doesn't tolerate much cold but it grows very fast. About six weeks from planting until harvest.

I second the turnip recommendation, and would also add beets, onions, and potatoes to your list. The onions may eventually bolt if they don't get enough water. If you have enough water to grow tomato plants, then these should work. I've also had success with wheat, which just thrived in oppressive heat and just a few rain events.
I also *highly* recommend shade cloth for leafy greens if you're in an area that gets a lot of sun. I use 30% shade cloth (i'm at a high elevation too, so the sun is extra intense) and helps immensely, especially when the plants are young.

But while they are not going to win the county fair, they are still slightly better than store bought (a 7/10 vs a 6/10). Which to me is good enough, and then they will back cross with whatever seedlings show up from your compost.
