These are hotdogs in a spicy red sauce. This is my mom's creation and we love them! Recently my hubby and I had a craving for them but didn't have any hotdogs so we cut up a ring bologna in chunks and covered it in the sauce and baked it - YUM!! There is a lot of room to play with the ingredients: mustard could be the yellow stuff or dijon; relish could be sweet or dill; diced onion could be fresh or dehydrated; vinegar could be white, red wine, cider, etc. ENJOY and make this your own!
I have been making this dressing for almost 10 years now. It is incredible and very easily tailored to everyone's liking. You can add more of certain ingredients and omit the ones you don't want or don't have available. My measurements are somewhat approximate as I have gotten used to just shaking the spice bottles over the mixing bowl and adding more of certain ingredients to get it to my taste. So by all means, use the mayo/milk as a base for your special dressing and run with it!
