3 cups idaho potatoes, peeled, boiled and cut into cubes when cool

Preheat oven to 350 degrees.  Cut skinless smoked sausage in half, lengthwise, and then chop into 1/2 inch "half moon" cuts. Cook in a frying pan for about 15 minutes, turning frequently to SLIGHTLY brown.  Meanwhile, put cooked & diced potatoes in 2 quart casserole. Add cooked meat and give it a gentle toss.  Mix all remaining ingredients (except for shredded cheddar cheese & the paprika) in a saucepan over medium heat until warm, melted and smooth.

Sprinkle shredded sharp cheddar cheese on top, and then sprinkle paprika evenly over the top.  Bake for 35-45 minutes (watch, until golden brown on top).  Serve.
