Serve it hot tonight with this Louisiana-inspired rice recipe! Just brown ground beef over medium-high heat and drain. Stir in onion, red pepper, and celery. Cook until vegetables are crisp-tender. Stir in Knorr® Cajun Sides™ - Dirty Rice and cook, stirring frequently, until rice is lightly toasted, about 2 minutes. Add water and bring to a boil over high heat. Reduce heat to low and simmer covered until rice is tender, about 7 minutes. Serve with hot pepper sauce.
