Heat the avocado oil in a skillet over medium-high.
Add the ground beef, breaking it into small pieces. Season with salt and pepper.
Cook 4 to 5 minutes, until deeply browned and crispy in spots. Leave it alone at the start. It needs to sit and build a crust before you break it up.
Drop the heat to medium-low and add the butter.
Whisk the eggs with a pinch of salt and pour them into the skillet around the beef.
Stir gently, folding the eggs as they set, about 2 to 3 minutes for soft curds.
Pull it off the heat while the eggs are still slightly wet. They finish on the plate.
Slide onto a warm plate. Chives and flaky salt on top.
