Preheat oven to 350 degrees. Grease a 8x11 inch casserole dish.
In a small bowl, combine the salsa, cilantro, and drained black beans. In a second bowl, combine the green sauce, chili powder, cumin, oregano and kosher salt. Set the second bowl aside.
Assemble your enchiladas. You will need the tortillas, refried black beans, bean/salsa mixture, and one cup of the cheese. On a single tortilla, layer in the following order, in the center of the tortilla: refried black beans, then bean/salsa mixture, then cheese. Roll the enchilada up tightly, then place in the prepared dish. Repeat with the other 5 tortillas. You should spread out all of the ingredients evenly amongst the six tortillas - if you have extra, open one up and put it in there.
Pour the green sauce mixture evenly over the top. Then spread the remaining one cup of cheese over the green sauce.
Bake for 20-25 minutes uncovered, or until the cheese is melted. Remove from oven and let cool for 5 minutes before serving.
Jalapeno Crema
While the enchiladas are cooking, combine the Mexican crema and the jalapeno in a small bowl.
