Place a large heavy-bottomed pot over medium-high heat with 2 tablespoons of the EVOO. Add the bacon to the pan and brown, about 3 to 4 minutes. Add the chicken to the pot and brown, 5 to 6 minutes, stirring occasionally to break up the lumps. Add the pureed chipotle, cumin, coriander, and smoked paprika, then stir for 1 minute. Add the onion and garlic to the pot and cook until tender, 5 minutes more. Add the tomato paste and chicken stock and some salt and pepper to the pot and bring the liquids up to a bubble. Reduce the heat to a simmer.
