Heat pellet grill or smoker to 250℉ with your choice of pellets or wood.
Place block of cream cheese on a small foil-lined sheet tray. Sprinkle the top of the cream cheese block evenly with about ½ tablespoon Spice That Jalapeno All-Purpose seasoning, or your favorite all-purpose seasoning. Place the two whole jalalpenos on the sheet tray alongside the cream cheese block.
Break up ground beef into small chunks and spread out in an even layer on a separate small foil-lined sheet tray.
Place the tray of ground beef and the tray of cream cheese directly on the grill grates, and smoke at 250℉.
Make the refried beans - While the beef and cream cheese are smoking, heat a large skillet over medium-low heat. Add 2 tablespoons bacon grease or cooking oil. Sauté the onions in the skillet until tender and lightly colored, about 5-6 minutes. Then add minced garlic and sauté an additional 1 minute.
Add the 29 oz can of pinto beans with the juice to the onions and garlic. Heat about 2 minutes, and add 1 tablespoon Fiesta That Mexican seasoning. Then use a potato masher or spatula to mash to desired consistency.
Add the can of refried beans, and mix all beans together. Continue to cook and mash until desired consistency is reached. Season with salt and pepper to taste.
After 1 hour and 15 minutes on the smoker, remove the tray of smoked ground beef, but leave the cream cheese on to continue to smoke. Transfer ground beef to a large skillet. Continue to brown the beef over medium heat, while breaking the clumps apart into smaller crumbles, about 5-7 minutes. Drain the beef and stir in 2 tablespoons Fiesta That Mexican seasoning (or your favorite taco seasoning) plus ½ cup water. Stir together well and continue to cook until sauce is reduced.
Make the cream cheese mixture - Remove the smoked cream cheese from the grill and transfer to a large mixing bowl. Allow the smoked jalapenos to cool a bit, then seed and dice. Add the diced smoked jalapenos to the cream cheese, along with 8 oz sour cream and the can of drained green chiles. Stir together well.
Adjust the pellet grill or smoker temperature up to 300℉ to heat while you assemble the dip.
Assemble the Texas Trash Dip with ground beef - Spread about half of the refried beans into an even layer in the bottom of a 12" cast iron skillet or grill-safe casserole dish. Then sprinkle about half of the smoked ground beef crumbles on top.
Spread about half of the cream cheese mixture on top of the ground beef layer. Sprinkle with about ⅓ of the shredded cheeses.
Continue to layer the other half of the ingredients, creating a second layer of each - the remaining refried beans, smoked beef crumbles, and cream cheese mixture. Then sprinkle with the remaining shredded cheeses. Place the skillet on the smoker, and cook at 300℉ for about 30 minutes.
Adjust the grill temperature up to 350℉. Top the dip with fresh or pickled jalapeno slices for garnish. Continue to cook at 350℉ for another 15-20 minutes, or until the dip is hot and bubbly and the cheeses are melted.
Carefully remove the dip from the grill. Allow to cool about 10-15 minutes before serving with tortilla chips or corn chips.
