In a large bowl, combine the chopped shrimp, cheese, green chilies, onions, olives and diced jalapenos (if desired).
Combine the mayonnaise, garlic powder and cumin; add to shrimp mixture and toss to coat.
Start the Traeger on Smoke with the lid open until the fire is established (4 to 5 minutes). Preheat to 350 degrees F with the lid closed for 10 to 15 minutes.
Spread out the tortilla scoops on a large baking sheet and drop the shrimp mixture by tablespoonfuls into each scoop.
Place the baking sheet on the Traeger grill grate and cook for 5-10 minutes or until cheese is melted.
Serve warm with sour cream and cilantro. Enjoy!
