Here's my typical hotdog bun that I've been using lately. Instead of buying all sorts of different rolls for burgers, hotodogs, and other sandwiches, I simply stock up on Italian bread. The long loaf style. Then cut it and slice it to suit what I'm using it for.
Example below. I cut a the loaf about 6 inches long, slice it lengthwise to form 2 separate hotdog rolls, and then cut a V groove to cut out/remove the center portion to make space for a hotdog. Toast it just a bit, add the hot dog & topping. Delicious!
This is not something I'd want to do for serving many hotdogs, but for just 1 or two at a time, it works just fine.
BTW: The fries are a work in progress, fried in 50:50 Beef Tallow & Coconut oil.
Flavor is fantastic, working on getting a bit more crispy.
