Prepare the cup of dried Quinoa according to the package directions. Start the grill or oven to preheat at 375 F.
Chop the tops off of the bell peppers and clean out the membranes and seeds. Set aside.
Once the quinoa is cooked combine it with the tomato, tomatillo pepper, garlic, black beans, chili powder, cumin, coriander and salt.
Stuff each of the peppers with the mixture and finish with a squeeze of lime over the top of the quinoa once it is in the pepper.
If you're grilling the peppers, set them on top of tinfoil to keep them in place and grill for 30 minutes.
If you're baking the peppers, set them inside of a baking dish and bake for 25 minutes at 375.
Five minutes before the peppers are done sprinkle the tops of them with Taco blend cheese and continue to grill or bake.
