Substitute for sport peppers?
Every now and then, I want to make a Chicago-style hot dog, but here in the Sacramento area, I can't get sport peppers at my local grocery store. So, short of ordering them via the internet, what would make a good substitute for sport peppers? Wax peppers? Pepperoncini? Come to think of it, what kind of peppers are sport peppers to begin with??? Thanks in advance to all who answer! :)
