Preparation

• Toss the avocado, about one-quarter of the onion, 2-1/2 Tbs. of the lime juice, and 2 Tbs. of the cilantro in a medium bowl. Season with salt and pepper to taste and set aside.
• 在食品加工机中，将1杯豆类，西红柿及其果汁，碎屑和阿多博酱混合在一起，然后加工直至光滑。搁置。
• Season the chicken with 1 tsp. salt and 1/2 tsp. pepper. Heat the oil in a large Dutch oven or casserole over medium-high heat until it’s shimmering hot. Add the chicken (the thighs should just fit, evenly spaced) and sear without touching until golden brown, 3 to 4 minutes. Flip and cook the other side until also golden brown, 3 to 4 minutes. Transfer to a large plate and let rest for 10 minutes.
• 取出锅，放在一边。鸡肉休息后，用手切碎或切碎。
• Return the pot to medium-high heat. Add the remaining onion to the pot and cook, stirring, until the onion begins to brown and soften, about 3 minutes. Add the chili powder and cumin and stir for 20 seconds. Add the beer and cook, scraping the bottom of the pan with a wooden spoon to incorporate any browned bits, until it almost completely reduces, 3 to 4 minutes. Add the remaining white beans and the puréed bean mixture and bring to a boil. Stir in the chicken along with any accumulated juices on the bottom of the plate. Cover, reduce the heat to medium-low and simmer for 15 minutes so the chicken finishes cooking and the flavors mix and meld. Stir in 1-1/4 cup of the cilantro and the remaining lime juice and season with salt and pepper to taste.
• Ladle into large bowls and serve immediately with a generous spoonful of the avocado mixture, a dollop of sour cream (if using), and a sprinkling of the remaining cilantro.

Serve with Mexican rice or cornbread.
