The smell of the leaves rubbed together create an intriguing smell that some are repelled by and others imagine cooking onions and bell peppers. Bladderpod flowers and seeds are edible. The seeds come out of the pods like peas. They are bitter and likely you would want to cook them before eating to bring out their sweetness. The pods and seeds contain glucocapparin which can be irritating to the skin. Cooking destroys glucocapparin. 

Some Native Americans relished the seeds and flowers for food. The immature peas inside are fresh and juicy, and can be harvested like garden peas but should be eaten raw in moderation. They can be used as capers. The flowers are edible too, but they reportedly need to be cooked for four hours to remove bitterness and reveal their sweetness. The young pods taste similar to a very mild jalapeno pepper.
