Prep this stew before leaving for the day. Let the slow cooker do the work for you, and a delicious Mexican-inspired meal will be ready when you return. Serve stew topped with panko mixture and garnish with cilantro, if desired.
In a nonstick skillet, heat 2 Tbsp. oil over medium heat. Add chicken and cook until browned, turning once, about 8 minutes total. Drain on paper towels and transfer to slow cooker. In the same skillet, cook poblano peppers, stirring, until golden in spots, about 3 minutes; add to slow cooker. Add chorizo, beans, chipotles, adobo sauce, tomatoes, salt, pepper and 1/2 the chopped garlic to slow cooker. Stir together, cover and cook on low until chicken is cooked through, about 4 hours.
Once chicken is cooked, heat remaining 2 Tbsp. oil in a medium skillet over medium heat. Add panko and remaining garlic. Cook, stirring, until mixture is golden and crispy, about 3 minutes.
