Couscous is low in oxalate at 1 mg per cup — essentially zero. It's made from semolina wheat, which is refined (bran removed), meaning the oxalate-containing part of the grain is gone. It cooks in 5 minutes (just add boiling water and cover), making it the fastest whole-grain-ish carb you can make. Use it as a base for stews, as a side dish, or in salads. From an oxalate perspective, couscous is a safe, quick carb option.
