5lbs potatoes (russet, red, or Yukon Golds) 3/4 stick margarine 1 cup mayonnaise (I use Kraft light) 1 8oz container sour cream 1 12oz pkg shredded cheddar cheese 5 slices cooked bacon (cut into bite size pieces) chives (enough to add color) salt and pepper to tastePeel potatoes, cut into large cubes, and boil until "almost" done in a large dutch oven sized pot. Heat oven to 400 degrees - Fahrenheit Drain potatoes and return to pot. Cut 3/4 stick of margarine into slices and drop onto hot potatoes. Add mayonnaise, sour cream, cheese, bacon, chives, and salt and pepper. Stir until well mixed. Spray 13 x 9 glass pan with non-stick cooking spray. Pour potatoes into pan, spreading out evenly. Bake at 400 degrees for approximately 1 hour. Great dish for company or pot luck!
