Preheat your Traeger grill to 225* with the super smoke feature enabled
Place the tenderloin pieces directly on the grill grates and close the lid
Allow the meat to smoke for about 15 minutes
Transfer the meat to a cutting board and using a sharp knife, cut into ½ inch pieces
In a bowl, toss the chopped meat with cumin
Preheat a cast iron pan to medium/high heat
Turn up the heat of the Traeger to high (350*) and close the lid
Cook the bacon slices in the hot pan until almost crispy
Transfer the bacon to a paper towel, leaving the bacon grease in the pan
Roughly chop the bacon and set aside
To the hot bacon grease, add the seasoned steak pieces
Cook until browned on all sides, about 5 minutes
Transfer the beef back to a bowl
In the same pan, add the onion and garlic and cook until just translucent, about 5 minutes
Add the red bell pepper strips and corn kernels
Stir well and then cover to cook for about 5 minutes
Remove the lid and stir in the chopped tomatoes and chopped green chilis
Cook for 10 more minutes, until the veggies have softened and the browned bits on the bottom of the pan have released, stirring well
Add the seared steak back to the pan and mix to incorporate
Top the dish with the chopped bacon and then a generous coating of shredded cheese
Return the pan to the hot Traeger and cook for 10-15 minutes until bubbly and the cheese has melted
Serve immediately with warmed tortillas, crumbled cotija cheese, chopped cilantro and drizzles of crema and a wedge of lime
