Depends on the location (duh!).

Here in zone 4b central NY, from most to least calories I grow potatoes, corn, squash, carrots,  parsnips, and beets. If one likes or dislikes one veg more than another this list could be shuffled accordingly. In 2015 I grew all my own food for one year (actually started planning for the experiment in 2014). I seem to have permanently turned myself off to turnips and rutabagas with that exercise as those two veggies and pork were all I had left for most of the month of June. If I were to do it again I'd definitely grow more potatoes and more corn than I did. Those two staples are easy to make into a base for other flavors to modify. Given the choice between a potato and a turnip I always seemed to choose turnip, until I ran out of taters... It was crazy to have a ton of things going in the garden in June, but almost not calories coming out of it.

For spicing life up a little bit lettuce, kale, aspargus, mustard greens, green beans, melons, raspberries.

Other good options that should be included if one has more acres - nuts, oaks (corn acorn bread is super good), fruit trees.

In my experience American hazelnuts are more variable in flavor than European. Were they bitter last year?

Perhaps this is due to a long history of domestication on the European front.

I also like bamboo. The density, speed, and evergreen nature are a triple whammy to overcome the viewshed problem described. Also the price will be right. The OP mentioned she didn't want to spend a bunch of money on purchased ornamentals. While buying enough rhisomes to establish 500 ft of fenceline would cost $$$ too, it's entirely possible there are some stands around whose owners would let you dig rhizomes for free.

Containment is not hard with either livestock or lawnmower. Cutting the new canes as they emerge will effectively stop the bamboo's spread.

I'd also go for a Phyllostachus or two.

I'm trying to grow more bamboo than I currently have! https://cairncrestfarm.com/blog/bamboo-yield/

Have you done a soil test? Which type (modified morgan, Melich III, aqua regia, etc)? Tests are not terribly expensive and can help you address deficiency and imbalance. If this is soil you're going to eat many of your yearly meals from you owe it to yourself to amend as needed with minerals.

Does anybody here graze bamboo with their cattle during the winter? I have a small test planting, but I'm borderline for where even hardy bamboos can hack it (zone 4). Here's a link to a blogpost and youtube I made about my experiment - http://cairncrestfarm.com/winter-grazing-browsing/

I haven't had sheep for a long time, about a year, but I've been running mine with my cattle. I use a free choice mineral mix and have had no problems. When I first put out the free choice feeder (used to use a mineral mix) the copper and selenium both got "hammered" for almost two months. After that the consumption declined and seems to deplete at about the same rate as the other micro minerals. Both Cu and Se are low in my soils, so it didn't come as a shock...
