You can use any kind of hot dog. Kosher hot dogs are good. If you want to take the recipe up a notch, try it with a mild bockwurst sausage.
1 Tbsp butter (more if needed)
6 standard sized hot dogs (plan 1-2 per person, or fewer if you are serving kids), sliced into 1/4-inch to 1/2-inch thick slices
1/2 cup chopped yellow or sweet onion
2/3 cup sour cream
1/3 cup of water
1--Melt butter in a large skillet (cast iron works well for this purpose) on medium high heat. Add the chopped onions and sliced hot dogs. Cook, stirring occasionally, until the onions and the hot dogs are nicely browned, 5-10 minutes.
2--Add the sour cream and water, stir until creamy. Heat until steamy.
Serve with cooked egg noodles, elbow macaroni, or favorite pasta.
