In a small bowl, stir together the chili powder, cumin, salt, black pepper, paprika, garlic powder, onion powder, red pepper flakes, and oregano.
Heat a large skillet over medium-high heat. Add a little oil if needed, then add the ground chicken. Cook, breaking it apart, until no longer pink.
Reduce the heat to medium. Add water or chicken broth, then sprinkle in the seasoning blend. Stir well until the chicken is evenly coated and the spices turn saucy, about 1 minute.
Stir in the adobo sauce and salsa. Simmer for 3–5 minutes, until slightly thickened.
Add the cream cheese and stir until melted into the chicken mixture.
Fold in the cooked rice and shredded cheese. Stir until creamy, cheesy, and combined. Taste and add more salsa or adobo if needed.
Spoon the filling into the tortillas and roll into burritos.
Heat a skillet over medium heat with a little butter or oil. Place the burritos seam-side down and cook for 2–3 minutes per side, until golden and crisp.
Serve warm with extra salsa, sour cream, queso, or guacamole if desired.
