Steak And Peppers in black bean sauce- adapted from Closet Cooking

Another great dish find is this Steak and peppers in black bean sauce. I've made this several times now and adapted the recipe from Closet Cooking. I improvised using black bean garlic sauce found in the Asian section of the grocery store instead of the fermented black beans. Kevin has informed me fermented black beans can be found in the Asian supermarkets. I also used two tablespoons of chili pepper flakes and two tablespoons of chili garlic sauce for an extra punch.
