Place the tomatillos and chiles on a baking sheet and set under the broiler until they are completely charred, soft and mushy, anywhere from 8 to 10 minutes.
Place the roasted tomatillos and chiles along with the garlic, onion, salt and pepper in the jar of a blender. Remove and discard the stems from the whole cloves, and add the tops or “berries” (may have already been crumbled) into the jar as well. Add 1 cup of the reserved pork broth and puree until completely smooth.
Heat the oil in a large casserole over medium-high heat. Once hot, but not smoking, add the tomatillo puree. Cover partially with a lid and cook for 10 minutes, stirring occasionally, until thickened considerably and has deepened in color.
In the jar of the blender, place the epazote, parsley and hoja santa along with remaining 3 cups of broth, and puree until completely smooth. Add to the casserole with the sauce and stir. When it comes to a simmer, add the reserved pork chunks and beans.
Continue cooking at a medium simmer for 25 minutes or until meat is completely coming apart and mole verde has thickened again. Serve and let people garnish as they please with onion, radishes and squeezes of lime.
