Add the pepper, onion, cheeses, and the can of Rotel tomatoes (Do NOT drain first) to the skillet with the chorizo.
10 oz can of Mild Rotel Diced Tomatoes and Green Chiles
Stir to incorporate as best you can and then place the skillet in the Pit Boss cooking chamber set to 180°F or "Smoke."
Take care to not place the skillet directly in the center above the firepot or it may get too hot.
Stir the queso every 10 minutes or so until the cheese has mostly melted and continue to smoke at this temperature for 1 HOUR.
After an hour on the Pit Boss, increase the temperature to 260°F to cook for the last 10-15 minutes to get the queso nice and hot to serve.
If the queso appears to have gotten more thick than you would like, you can add up to ¼ cup of beer to thin it back out. Make sure to stir well afterwards.
¼ Cup Beer
Carefully remove the smoked queso dip from the Pit Boss to a heat proof surface or trivet.
Optionally top with extra diced tomatoes and chopped cilantro
Diced Tomatoes , Fresh Chopped Cilantro
Serve with tortilla chips directly from the cast iron skillet.
