They do get *some* veg, apparently:

"food n. The Sami diet is simple and healthy. It consists of fish caught in lakes, rivers and the ocean, reindeer meat that is dried in the sun, smoked, or cooked in a stew with potatoes, and cloudberries and mushrooms gathered from the forests and bogs. Shredded carrots, sliced peppers amd bok choy often accompany a Sami meal as do bread, cheese and coffee."
