Heat the oil in a sauté pan or a cast iron skillet over medium heat. Add sausages and break them in small pieces with the back of a wooden spoon. Cook stirring constantly until sausages starts to brown.
Add onions, bell peppers, fresh jalapeño and garlic. Stir everything for about 5 minutes or until onions and peppers starts to soften.
Add the sausage mixture to the pan.
Add canned tomatoes, cheeses and pickled jalapeños. Sprinkle with cumin, fresh cracked pepper and chipotle powder.
Place the pan on your preheated smoker at 350°F (175°C) for about 30 minutes.
Stir the ingredients to combine and keep cooking for another 20-30 minutes stirring once or two more times in between.
You will see the smoked queso is ready when everything is combined and the queso is melted and bubbling on the edges of the pan.
