Chicago Hot Dog 8 hot dogs 8 hot dog buns 2 tomatoes, sliced 16 pepperoncini peppers 1/2 cup onion, chopped 1/2 cup sweet pickle relish Cut tomatoes into thin slices, then cut in half to make half circles. Grill hot dogs over a medium-high heat until browned, about 4 to 5 min, turning occasionally. Open hot dog buns and grill for 1 min, cut side down. Assemble dogs by placing 2 slices of tomato on the bun, then the hot dog, and then the peppers. Now top with mustard, onions and relish. Sprinkle on some celery salt and that’s a real Chicago Hot Dog.
