Bet - I have very little vegetable gardening space with some sun exposure. But, that space has to share with a few roses, perennials and shrubs. I've taken to growing vegetables in containers over the past couple of years. I started small with Burpee's Kaleidoscope small carrots and tomato 'Reisentraube' (because the seeds were free). Then I moved on to kale, Swiss chard and Napa cabbage. For this coming year, I've done a little research on summer squash and zucchini that I can grow in pots since they take up more space in the ground than I allotted. I'm also going to try potatoes for the first time ever - those will go in grow pots. The main thing to remember is that the containers will require more water during the growing season. I hesitate to recommend specific varieties because your summers get a lot hotter than mine. You can search for "patio" and name your vegetable/fruit for some recommendations online.
