Remove the stem and seeds from the Anaheim pepper and slice vertically through one side of the peppers so they will flatten out. Set aside.

In a mixing bowl, combine, ground beef, egg yolk, salt and pepper.

Press ground beef mixture into three patties.

Grill hamburger patties and Anaheim peppers.

Internal temperature for the hamburger patties needs to be 160° and the peppers need to be tender.

When patties have cooked through, turn heat down on the grill and top with pepper jack cheese and allow time to melt. Top with a layer of cream cheese and allow time to warm cream cheese.

Remove from grill, place on a bun, top with Anaheim pepper, lettuce, tomato, onion, pickles, and any condiments, as desired. Enjoy!
