I ate some raw, I tried some in vegetable soup (with turnip seeds as the "spice"), and I boiled some of them. All together probably 20lbs of them.
All they're really good for that I can see is to put in soup with meat, but in that case they aren't really adding much nutrition - they just let you make soup since it requires vegetables.
A Njerpez raider camp popped up right near my house, so I put on my long mail hauberk and iron great helm over my standard set of bear fur (hood, shirt, leggings, footwear, mittens), grabbed my northern bow with two dozen arrows and my battleaxe, and set off to war.
There were eight of them in total. I approached silently from the north, and immediately spotted one outside his Kota. While hidden, I put an arrow in his skull - killing him instantly. The fellow that was beside him and just out of sight must have seen this and alerted the others, as he rushed toward me with his own bow. Soon I had five of them coming at me. One had a hunting bow, two had shortbows, the other two were rushing me - one with a spear the other with a broadsword. I put three arrows in the one with the hunting bow, the third hitting his skull - apparently knocking him out. I then shot one of the fellows with a shortbow in the arm, making him drop the bow. During this time the two melee were closing on me, and the three archers had been shooting me the entire time. I had taken a few hits, but so far was only sporting a minor (2%) puncture to the left shoulder from the one with the hunting bow - thanks to my armor the other hits were bouncing off.
As the one with the sword closed in, the spearman right beside him, I put two arrows in his leg - making him stumble. The spearman rushed forward and jabbed me in the right hip as I was readying my battleaxe, but the armor stopped it from penetrating too much - causing only a minor (2%) puncture. I then hit him hard in the leg, causing him to fall, and quickly cleaved him in the head - killing the spearman. The swordsman was right behind him, and I assume from the wounds to his leg he stumbled and fell when he tried to hit me with his sword. I quickly cut him in the head as well, killing him too. At this point two more had apparently heard the commotion and were approaching me, and the archer who had dropped his bow was closing in with a knife. The other archer was firing away to little effect, his shortbow apparently not powerful enough to penetrate my combination of mail and bear fur. I rushed the archer with the knife and scored several good hits with my axe before he turned to run. He fled as the two new faces approached. I stepped back a few steps and picked up the arrows all over the ground that the archers had been firing at me, put away my axe, and started firing my bow again - quickly putting an end to one that had a battlesword with a few shots to the head. The other was carrying another hunting bow, and I shot it out of his hands with a shot to the arm. He switched to his scimitar and rushed at me.
At this point there were three left - one archer with a shortbow who had apparently ran out of arrows and was rushing me with a spear, one archer who was running away badly wounded with a knife, and a slightly wounded one with a scimitar. I swapped back to my battleaxe and hacked the one with the spear in the leg twice, he fell on the second hit and I quickly finished him with a chop to the neck. The one with the scimitar was right behind him, and I did much the same to him - a few hits to the legs followed by a lethal blow to the head. I quickly dispatched the poor unconscious archer that had been out cold the whole fight, then readied my bow and ran across the camp - chasing down the last wounded one and putting three arrows in his back.
I searched the camp, carefully checking the Kota and three houses and then the surrounding area. Satisfied that no more were alive, I dismantled the kota and used the wood to set fire to the three houses (after grabbing the loot out of them, ofcourse - I found a shiny necklace in one). I then gathered up a few scraps of clothing from the bodies of the fallen for the cloth, bandaged my two minor punctures, and headed back home. I noticed while leaving that the icon of the camp was gone, as was the pink cultural region indicator on the map - so I believe I've successfully fought off their little incursion into my territory.
I took so many hits to the chest area that my long mail hauberk and bear fur shirt were pretty badly damaged, yet I only had the two very minor puncture wounds. The armor certainly served its purpose. The fur was down to about 80% durability, and the mail is down to about 85%. Luckily I had extra bear fur to repair my bear fur shirt, but I don't have a way to repair the mail. Oh well, I can always travel back to the Driik to buy another when it eventually wears out.
