Place the tomatillos and jalapenos cut-side down on a foil-lined baking sheet. Scatter onions and garlic around tomatillos and jalapenos.
Place under broiler for 5-7 minutes or until skins on tomatillos blacken.
Remove, and when cool, pour tomatillos, jalapenos, onion and garlic, including any juices, into a food processor. Pulse until well blended.
Heat a large stockpot to medium heat and add tomatillo mixture and chipotle pepper. Stur around for a minute or two, and add turkey, beans, broth, beer, tomatoes and seasonings. Bring to a boil, and reduce to a simmer. Allow to simmer, stirring occasionally, for 20-30 minutes to allow flavors to blend.
Immediately before serving, taste and adjust salt and pepper seasonings as necessary, and stir in most of the cilantro, reserving a bit to use as garnish.
