4 med. potatoes
1/4 c. salad oil
1/4 c. butter
3/4 c. sour cream
1 tbsp. flour
1/2 lb. jalapeno cheese, shredded
1/8 tsp. pepper
1/3 c. Parmesan cheese
3 tbsp. chopped parsley
Paprika

Put oil and butter in microwave-safe dish. Microwave on high for 1 minute. Peel potatoes. Rinse and cut into small cubes. Add to dish; stirring to coat with butter. Push potatoes towards the outside edge of dish, leaving a clear spot in the center. Sprinkle with paprika. Cover with lid or plastic wrap. Microwave at high for 12 to 15 minutes. Let stand for 5 minutes. Potatoes should be soft enough to mash with a spoon. Cover and microwave 2 to 3 minutes longer, if necessary.

In a small bowl, smoothly blend sour cream and flour. Add to the potatoes along with the cheese and pepper. Stir gently to mix. Spread out in an even layer. Sprinkle Parmesan cheese over top. Cover and microwave at medium high heat for 5 minutes.
