This would be a good recipe to try if you want potatoes with your franks but do not want to make scalloped potatoes. It is from Budget-Wise Dinners That Are Winners- Thrifty Main Dishes, 1979.
Hot Dog Mash
1/3 cup butter or margarine
1 cup chopped onion
1/2 cup chopped green pepper
1 clove garlic, crushed
1 pound frankfurters, cut into bite-size pieces
1-1/3 cup instant mashed potatoes
1/2 cup grated American cheese
1/4 cup grated Parmesan cheese
Melt butter or margarine in medium skillet over medium heat; add onion, green pepper and garlic and saute until tender, about 5 minutes. Reduce heat to low and add frankfurters; cook, covered, for 5 minutes, stirring occasionally. Meanwhile, prepare instant mashed potatoes according to label directions to yield 4 servings; stir in 1/4 cup of the American cheese and 2 tablespoons of the Parmesan cheese.
Place frankfurter-onion mixture in lightly greased 1-1/2-quart casserole; cover with potato mixture. Sprinkle with remaining American and Parmesan cheese. Bake at 350 degrees for 30 minutes.
