Heat oil in a Dutch oven or large saucepan over medium heat. Add bulgur, onion, cabbage and carrots; cook, stirring, until the vegetables begin to soften, about 1 minute. Add broth and soy sauce (or tamari); bring to a boil. Reduce heat to low, cover and simmer until the bulgur is tender and the broth is absorbed, 10 to 15 minutes. Serve hot, sprinkled with peanuts and parsley.
