It's super easy to plant: push a shovel into the ground, wedge it forward to open a crevice in the soil, drop a sunroot in, and carefully pull the shovel back out. Pat the soil down with your foot. No need to dig a hole! Give it some mulch, and if you live in a dryland area, give it some shade as well.

Easy to harvest: they're mostly just under the plant stalks and are easy to get to and pull out.

Easy to propagate: just harvest some and eat them. If you like them, take some harvested tubers and plant them somewhere else.

Basic cooking recipe: wash and then boil some sunroots for at least half an hour and mash them. Add a little whole wheat flour, some shredded onion, an egg, and a little baking soda and mix. Put some mix into a skillet like a thick pancake and cook similarly, but a bit longer. The flavor is very mild so you can top it with guacamole or a lightly cooked sunny-side up egg or whatever you like. I bet some soy sauce mixed with chili pepper sauce would be nice.

Here's a video from Canadian Permaculture Legacy showing how to make Ukrainian Deruny with sunroot instead of potato:
