Use the wide (18" ?) heavy duty foil and mold it to the outer part of the factory bucket. Remove and put molded foil inside the bucket and fold remaining foil over the edge. Cheap and gets the job done. If the bucket gets greasy, I just run it through the dishwasher.
For pellet grill chicken, I like it simple...kosher salt, cracked pepper and granulated garlic.
Serve it up with Alabama White Sauce...https://www.allrecipes.com/recipe/244944/alabama-style-white-barbecue-sauce/
Never done queso on the rec tec.
I don't have a recipe per se...it all depends on what I have on hand. I always start with a roux and make a basic cheese sauce with butter, flour, whole milk, and hand grated sharp cheddar and Wisconsin Brick cheese. Pre-shredded cheese is awful stuff.
I've tried to like chorizo, but I just can't. It's too greasy and never cooks up as good as some good hot Italian sausage.
Spanish style chorizo (rather than Mexican) is a totally different animal...much better
There's no axle on the old design either...look up the wheel mod...you drill your own holes and supply your own threaded rod for the axle. Looks like it should be just as simple.
