I saw this thread the other day and thought I'd give them a shot. When I was looking over the hotdog selection in the store I also saw the Oscar Meyer 98% fat free made with turkey (40 cal, 1g fat, 15mg cholesterol, 470mg sodium, 3g carbs, 5g protein). I bought both to try. And I thought the Oscar Meyer's tasted more like our pre-Alli dogs which were Ball Park beef franks. I had thought the kosher beef dogs would come closest, but they tasted too strong to me.
But thanks to the OP for at least making me realize that there are amazing substitutes for things I thought were off-limits!
