I haven't tried this one but it's on my to do list ... I would very likely use 1/4 or 1/2 the cumin they are calling for (start small, adjust up by taste) but otherwise it sounds real good to me:
1T dry mex oregano leaves
2t ground cumin
1t sage
1/2t cayenne
1/2t black pepper
3.5lbs lean pork loin
1/4C veg oil
2 med onions diced
6 - 8 cloves minced garlic
2 bay leaves
1qt chicken broth
10 green chiles roasted
2 - 8 jalapenos
6 carrots peeled, cubed (stew size)
3 medium russets, peeled, cubed (stew size)
1/4 fr chopped cilantro (stems removed)
salt to taste
Cube pork into 2" chunks, mix first five ingredients and mix well into cubed pork. Lightly brown cubed pork in hot oil, remove pork from skillet. Soften onions, add garlic when onions nearly done, let garlic cook a bit then add broth and bay leaves and pork. Simmer 30 minutes covered. Stem seed and chop green chiles and jalapenos, add to broth, simmer covered for 45 minutes. Add root veggies, simmer until tender. Add salt and cilantro taste and remove bay leaves shortly before serving.
For the chiles I'd use a mix: some anaheims and maybe a poblano or even some green bell pepper. Roast them black under the broiler or on the grill over mesquite or hickory until good and black and the outer tough skin has bubbled well. Quickly rinse under cool water then peel and dice large.
To adopt to use leftover PP add the spices to broth, then add PP near the end when the root veggies are almost done (don't brown the PP in spice mix).
