One of the things I have loads of luck with is herbs. I grow two varieties of Thyme, Savory, Marjoram, two varieties of Sage, two varieties of Basil, Oregano, three sets of chives, parsely, cilantro, and Rosemary (the only one I have trouble keeping alive). I dry all of them to use year round. The thyme, savory and sage all get used regularly in sausage making.
Trying a different experiment this year, growing lots of tomatoes and peppers in pots. Have beets and leeks going in a berm and some peas thrown randomly about. The neighbors lab has "fixed" some of our rabbit issues, much to the horror of his human children charges.
I am eyeing the beet tops as potential greens, but they are a few weeks off yet.
I swore to my wife once that if gas got to $4 a gallon, I was tilling up the whole yard (she has a huge area of flowers) for a garden. Grew up in a small town and I am recalling my folks only buying what we could not grow/raise. She is eyeing gas prices with worry ever since.
