I'd add to that list Blueberry bushes if you have the right type of soil (acidic/well-drained). They don't need pesticide spraying and each bush can grow up to 15 pounds/year of berries.

My yard project this fall is digging out a row of clay soil and making a raised amended bed for 8-9 blueberry highbushes. Blueberry plants are finicky about soil PH and drainage, so I am prepping the bed with sulfur, coarse sand, peat, and ground pine bark chips and getting it right for planting by spring 2012. I expect they will produce ~100 pounds per year in 5 years.
