Prepare the Components: In a small bowl, whisk together the smoked paprika, cumin, black pepper, turmeric, allspice, and sea salt. Set this spice blend aside. Drain the two cans of chickpeas, reserving ¾ cup of the liquid (aquafaba) and setting the beans aside. Pat the cubed chicken dry with paper towels.
Bloom the Aromatics: Warm the olive oil in a wide Dutch oven over medium heat. Add the diced sweet onion and cook, stirring frequently, for about 7 minutes until softened and translucent. Stir in the minced garlic and tomato paste, cooking for another 2 minutes until the paste darkens slightly and becomes fragrant.
Sear the Chicken: Add the cubed chicken to the Dutch oven, then sprinkle the entire prepared spice blend over the top. Stir to coat the chicken pieces evenly. Increase the heat to medium-high and sear the chicken, turning occasionally, for 6–7 minutes, until golden-brown on most sides. The chicken will not be fully cooked at this stage.
Deglaze and Build the Sauce: Pour in the undrained fire-roasted tomatoes and the reserved ¾ cup of aquafaba, scraping the bottom of the pot to lift any flavorful browned bits. This additional liquid from the chickpeas creates a richer, more cohesive sauce.
Simmer and Finish: Stir in the drained chickpeas. Bring the mixture to a steady, gentle bubble, then reduce the heat to low. Cover the Dutch oven and allow it to cook for 5–7 minutes, or until the sauce has thickened slightly and the chicken is cooked through, reaching an internal temperature of 165°F (74°C).
Brighten and Serve: Remove the pot from the heat. Squeeze the juice of the entire lime into the braise and stir to combine. Serve immediately, garnished generously with the chopped cilantro and mint mixture. This dish pairs beautifully with fluffy quinoa or warm flatbread.
