Ready, Set, Cook! Reynolds Wrap Contest Entry. What's better than grilled chillies? Grilled chilies stuffed with a beefy, cheesy filling. Hatch Chilies in season or Poblano peppers the rest of the year get a simple, tasty treatment in a recipe that yields a lot of flavor for very little work. Great for picnics and cookouts. These re-heat beautifully in the microwave so you don't need to be afraid to make the whole batch, but its easy to cut the recipe in half if you prefer. And if you are feeding anyone who can't tolerate hot peppers you can substitute Cubanelles or Italian Frying Peppers.
