Start with a few handfuls of potatoes,
slice into 1/4" slablets,
and fry in olive oil
Chop a handful of green onions
and fry in leftover oil.
Crack 7 eggs for a 10 inch skillet,
add a fair measure of salt,
And cook on medium heat for about 10 minutes, or until the edges look set. Then broil for 5 minutes (top will become fully set) and let cool for another 5.
