Heat oil in a medium pot over medium heat. Saute onion and bell pepper until tender, 6 to 8 minutes. Add chipotle and adobo sauce and cook for 1 minute. Add turkey, breaking it up with the back of a spoon, and cook until no longer pink, about 3 minutes. Add tomatoes with juices and beans.
Bring to a boil. Reduce heat and simmer, stirring occasionally, until slightly thickened, about 30 minutes (add water to adjust consistency). Season with salt and serve alongside garnish.
