Microwave ground beef in a plastic colander covered with waxed paper. Cook on high, stirring every 2 1/2 minutes, until ground beef is no longer pink. In a 3 quart casserole combine all ingredients. Microwave uncovered on high for 10 minutes–stirring halfway through cooking time. Reduce microwave to medium heat and microwave 20 minutes or until rice is soft.
