Bring the water and salt to boil in a medium saucepan. When water is boiling, stir in pinch saffron. Add the rice, reduce heat, cover, and simmer until rice is just tender (about 20 minutes).
Meanwhile, in a large bowl, blend vinegar and mustard with a fork. Pour in olive oil in a thin stream, whisking with fork to emulsify. Stir in the peas, bell peppers, parsley, and oregano. When rice is cooked, add it to the bowl and stir well to distribute dressing and ingredients. Let rice cool to room temperature and serve. Or refrigerate up to 1 day, then serve.
