baked potato and cauliflower soup for one

Made this for lunch the other day. Good stuff! It would be good with cheese added, too - I was going to and forgot.

1/2 c. chopped cauliflower
water
1 medium baked potato, diced
1/2 T. butter
1 cup milk (I used half milk and half fat free half and half for a richer taste)
salt and pepper to taste
pinch celery seed
1 tsp. dried minced onion
1/4 tsp. garlic powder

In a medium saucepan, steam the cauliflower in a bit of water until tender. Add the remaining ingredients, stirring to combine, and cook until heated through. Eat as is or process in a blender (or with a stick blender) to make it thicker.
