Heat a Carbon Steel Skillet over medium high heat. Add all of the vegetables, and char, until black in spots and softened. Add to a blender, and blend until it creates a smooth paste. Season with salt, to taste. Set aside.

Place your tostadas in a Non Stick Frying Pan over medium heat, and heat until and warm. Remove, smear guacamole on top of just one, and set aside.

In the same Non Stick Frying Pan, add the black beans and heat until warm throughout. Add the black beans to the tostada without guacamole.

In the same Non Stick Frying Pan, over medium-low heat, add your eggs, and cook them low and slow. Season with salt. Once it all comes together like an omelet, plate it spread out over both tostadas.

On top of the eggs, add your salsa verde, cilantro, and a squeeze of your lime.
