Why it works: Kidney beans and beans match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 364 recipes mention both. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
The recipe

Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Heat the olive oil in a large pot over medium heat. Add the chopped onion and cook about 5 minutes until soft, then stir in the chopped garlic and cook 1 minute more.
Add the drained whole peeled tomatoes and break them up with a spoon. Stir in the diced tomatoes with green chile peppers and the chicken broth, season with chili powder and cayenne pepper to taste, and bring to a simmer.
Add the chicken breast halves to the pot, reduce the heat to low, partly cover, and simmer about 60 minutes until the thickest part of the chicken reaches 165°F (74°C).
Remove the chicken to a cutting board and shred it with two forks. Return the shredded chicken to the pot.
Stir in the rinsed and drained kidney beans and black beans. Simmer uncovered on low for about 60 minutes, stirring occasionally, until the soup is thick and well flavored.
Ladle the soup into bowls and top each serving with shredded Cheddar cheese and a spoonful of sour cream.

Fit is the average pairing score against chicken, tomato, pepper, olive, onion, garlic, beans. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
