Preheat oven to: Cast Iron Skillet
Prep the white rice separately however you prefer. I use a rice machine. (Zojirushi ... huge fan)
Heat the olive oil in a large skillet over medium heat
Add the onion and bell pepper and let saute for 5 minutes. Then add the minced garlic (and corn if you have it) and saute for another 5 minutes
Add the black beans, water, cooking vinegar, salt, pepper, oregano and chipotle pepper. Stir everything in and let cook another 10 minutes.
Remove from heat. Serve in bowls on top of white rice.
