I love this one!
20 oz. frozen chopped broccoli
2 cups cooked rice
1 jar (2 oz) chopped pimentos, drained
1 cup finely chopped celery
1 cup sour cream
1 can (10 3/4 oz) cream of mushroom, broccoli or celery soup
1/4 tsp salt
1/4 tsp black pepper
1/2 cup shredded cheese (I used sharp cheddar)
Cook broccoli according to package directions. Drain and mix with all ingredients except cheese.
Pour into a 2 quart casserole dish and sprinkle with cheese. Bake at 325 for 20-30 minutes.
