Sure. It's so simple, you might have to change it a little to suit your eating plan, but here it is.
I do them two ways. I peel and cut the rutabaga into about a 1/4" dice and partially cook them in the microwave or parboil them. I like onions so I chop a few of those too. Sometimes I will dice up a couple of slices of bacon. When the bacon begins to brown and release the fat, I add the rutabaga and onion and salt and pepper to taste. They will brown up faster than potato so you have to watch them. If you don't want to use bacon then sometimes I use butter instead and even melt cheese on them occasionally. You see what I mean about my fat tooth. LOL.
I don't remember what the paleo diet says exactly about fats, but if I remember correctly he's not real big on dairy, so you could really use any type of fat or oil. A "fruity" olive oil might clash with rutabaga so if you use that I would use a less expensive olive oil with a more neutral flavor. I usually have them for breakfast topped with an omega egg.
Rutabaga sometimes vary a little in flavor, but the milder ones really taste a lot like potatoes.
