THIS IS THE IMPORTANT PART OF THIS STYLE OF HOT DOGThe trick is to grill the onions with Ketchup and Mustard!!! You'll start to smell beautiful L.A. ;)
BEWAREThe Serrano chilies DO get hotter when grilled. I used two per hot dog but for people who can't eat alot of chili, I recommend using 1/hot dog.
Why not throw in the bread after you're done with the onions?! Who doesn't love greasy food :)
Voila! Slap everything on top of your hot dog and squirt moooreee ketchup and mustard!
