1 med. head cauliflower (served whole)
2 tbsp. water
1/2 c. mayonnaise or salad dressing
1 tsp. finely chopped onion
1 tsp. prepared mustard
1/2 c. shredded Cheddar cheese

Place cauliflower in 1 1/2 quart glass casserole. Add water; cover with glass lid or plastic wrap. Microwave on high for 8 to 9 minutes or until tender crisp.

Combine mayonnaise, onion and mustard in small mixing bowl. Spoon mustard sauce on top of cauliflower. Sprinkle with cheese. Microwave on "roast" for 1 1/2 to 2 minutes to heat topping and melt cheese. Let stand 2 minutes before serving. Serves 6 to 8. Very elegant!
