I like the idea of relying on food plants found in my neighborhood. In my part of west Los Angeles there are many citrus trees and almost as many walnut trees. There are banana trees, cardoons, fennel, rosemary, dandelions. If I had a better nose, I'd probably have found the neighborhood bay tree by now. Between La Cienaga, Beverly, La Brea and Wilshire there are lots of avocado trees. What sort of food plants grow in the front yards and open lots of your neighborhood? The plants I have in mind are not being grown in French raised beds, are not harvested by their ostensive owners, often wither and die or drop their overripe fruit without anyone (but me) ever picking any.
