This is a good tabbouleh(塔博勒色拉Tǎbólè sèlā) alternative for those of you who can't tolerate wheat, though you must seek out a brand of steel-cut oats that has been processed in a gluten-free facility if you need to avoid gluten(gluten is a substance found in cereal grains such as wheat).
Unlike traditional tabbouleh, which is a really a parsley(parsley is a small plant with curly leaves that are used for flavouring or decorating savoury food) salad with a little bit of fine bulgur, this is more of a lemony grain salad with a generous amount of parsley and other herbs. For best results, toss the soaked oats with the dressing and refrigerate(if you refrigerate food, you make it cold, for example by putting it in a fridge, usually in order to preserve it) overnight.
