In a bowl, combine the chili sauce, onion powder, garlic powder, Worcestershire sauce, mustard, brown sugar, and pepper together.
With a small knife, make small diagonal cuts on the top and bottom of each hot dog, about 1/2 inch apart, cutting part way into the hot dog. The cuts should look like rounded half circle.
Add the marinate to a gallon sized zip-loc bag along with the hot dogs. Place in the fridge to marinate for 20 minutes or up to all day.
Cook the hot dogs on the grill until nicely charred and the cuts open up, about 4-5 minutes total.
