Linda's Potato Soup

Cook the following in 2 c water; bring to a boil & boil for 10 min. Stir so it doesnt stick.
2 c diced potatoes (I always use 3 c tho)
some shredded carrots & brroccoli (optional)
some diced onion (i think about 1/4 c)

In another Pan melt 1/4 c butter. Stir in 1/4 c flour till smooth. Stir in 2 c milk (can use some half & half). When starts to thicken, stir in 8 oz velveeta cheese till melted-or almost.  add this milk mixture to the cooked potatoes. Cook on low till combined well. Can add salt/pepper to taste
