Preheat to medium-high heat, around 375 degrees F. Set your smoke level to high so you can get the most smoke flavor in your queso possible.
Cut all your cheeses into ½" cubes so they melt nice and evenly. Even better if you can bring them to room temperature.
Layer your cheeses, meat, salsas, and veggies in your Dutch oven or disposable foil pan.
Place the pan on the smoker (or side of the grill) and cook for 1-2 hours. Stirring every 20 minutes to help incorporate evenly.
If your queso is too thick or you'd like to add extra creaminess, stir in some sour cream, milk, or heavy cream until you reach your desired consistency.
Serve with your favorite dippers like tortilla chips, frittos, or fresh veggies.
