Step 1

Heat olive oil in a medium skillet over medium-high heat until shimmering. Add in onion and sauté until lightly browned, about 5 minutes. Add in garlic and cook until fragrant, about 30 seconds. Add in chorizo, breaking sausage into small pieces with a wooden spoon, and cook until cooked through, about 5 minutes. Transfer mixture to a large bowl.

Step 2

Add rice, tomatoes, crema, cilantro, and cotija cheese to bowl with meat mixture and mix until combined. Season with salt and pepper to taste.

Step 3

Spoon mixture into cavities of split poblanos and top with pepper jack cheese.

Step 4

Light one chimney full of charcoal. When all the charcoal is lit and covered with gray ash, pour out and arrange the coals on one side of the charcoal grate. Set cooking grate in place, cover grill and allow to preheat for 5 minutes. Clean and oil the grilling grate. Place poblanos on cool side of grill, cover, and cook until cheese has melted and poblanos have softened, about 20-30 minutes. Remove from grill and serve.
