Using a medium sized pan over medium-high heat, heat the olive oil. Add the black beans and saute for about 5 to 6 minutes, or until very soft. Season with salt. Remove from pan and into a bowl. Using a potato masher, mash the black beans together until somewhat smooth.
To assemble: Spread the black bean mixture on the naan flatbread, then top in this order: sour cream, guacamole, salsa, lettuce, tomatoes, fresh bell peppers, and then sprinkle on some cheese, black olives and jalapenos. Enjoy!
