No doubt meat is nice but there are only so many chickens a suburban lot can support. I tried raising some pasture poultry to sell and it was a lot of work. Cattle are easier, they mostly take care of themselves, but they don’t really fit in suburbia. Potatoes contain all the essential amino acids. They’re one of the few foods that you can live on solely- not forever I assume but for a long time, some of my ancestors did. Once they get going they will shade out lots of weeds. Add some legumes and a small plot will keep your belly full and the rest of you going. Pole beans are great because they add the third dimension to your garden. Plant rows of corn too far apart then plant pole beans between the corn, you’ll get a little corn but a whole load of beans with little effort as they pull themselves up the corn stalk. You should plant corn in blocks, it likes to be close to more corn to get the best crop. It either needs to be soaked in lime to make hominy or masa to free up the Lysine. But corn is full of oil and protein.
