Combine the chicken and salsa in a medium bowl and toss to coat. Cover and refrigerate for 30 minutes.

Preheat the oven to 425 degrees F. Generously spray a baking sheet with cooking spray; set aside.

Heat 1 tablespoon of the oil in a medium skillet over medium-high heat until shimmering. Add the peppers and onions, season with a pinch of salt and cook, stirring often and lowering the heat if needed so the vegetables don’t brown, until softened, about 6 minutes.

Transfer the vegetable mixture to a plate and return the skillet to medium-high heat. Add the remaining tablespoon oil to the skillet and heat until the oil shimmers. Add the chicken and cook, stirring occasionally, until cooked through, about 5 minutes.

Remove the chicken from the heat and fold in the cheese and half the vegetable mixture. Fold the remaining vegetable mixture into the chickpeas along with the cilantro, jalapeños and avocado. Taste both mixtures and season with more salt if needed.

Combine the flour and 3 tablespoons water in a small bowl to create a paste that is the same consistency as glue, adding more water if needed. Halve the tortillas and cover them with a damp towel. Using the back of a spoon, spread a line of the flour mixture on the cut edge of a tortilla half. Fold the opposite ends of the tortilla half up and over, overlapping slightly to form a cone. Pinch gently to seal. Cover with a damp cloth and repeat with the remaining tortillas.

Fill a cone with 1/3 cup of the chicken mixture. Spread some of the flour mixture along the inside edge of the top of the cone, then pinch the two sides together to seal the pocket. Place on the prepared baking sheet seam-side down and repeat with the remaining cones, chicken mixture and chickpea mixture. (You should have 6 of each filling.)

Spray the pockets lightly with cooking spray. Bake, flipping the pockets once about halfway through, until golden and heated through, 15 to 20 minutes. Serve the pockets with sour cream, guacamole, hot sauce, lime wedges and more salsa.
