In a 10-inch cast-iron skillet, brown the beef over medium-high-heat, seasoning it with the salt, until cooked through, about 5 minutes, breaking up the meat with a spatula as it cooks.
Add the marinara sauce and stir well to combine. Push half of the sauteed beef off to one side of the skillet and place a layer of sliced chicken breast on the bottom of the skillet. Top the chicken with ½ cup of the shredded cheese. Scoop the beef on top of the deli meat to create an even layer. Top with the remaining ½ cup of cheese and sprinkle with the oregano.
