I will be the first to admit that I don’t eat Arby’s very often. Heck I don’t even remember how many years it’s been. What I do remember is that I really liked their Horsey Sauce.
I had some leftover roast beef I need to use so I decided it would be the perfect time to try and replicate their Horsey Sauce.
