"This hearty casserole is my favorite dish to make for a potluck. With the green of the broccoli and the rich cheese sauce, it's pretty to serve, and it makes a tasty side dish for almost any kind of meat." Margaret Mayes In a large skillet over medium heat, saute onion, celery and broccoli in butter for 3-5 minutes. Stir in cheese, soup and milk until smooth. Place rice in a greased 20 cm square baking dish. Pour cheese mixture over; do not stir. Bake, uncovered, at 160ºC or 25-30 minutes or until hot and bubbly.
