Heat a small non-stick pan over medium heat-high and add half of the butter or oil.
Add green beans and salt and saute until green beans and tender and slightly charred, about 5-7 minutes.
Turn heat down to medium and add arugula and saute just until wilted.
Add remaining butter or oil to the pan and swirl. Make space in the pan for two eggs, and crack eggs one at a time into a ramekin and pour into the spaces. Swirl so the white covers the pan, careful not to break the yolks.
Saute until the whites are set but yolks still runny. If you did it all right, slide the whole piece from pan to plate. If not use a spatula to move to a plate. Top with za'atar, harissa and whatever else you like and eat!
