Heat your olive oil over medium heat in a small frying pan.
1 tbsp olive oil
Scatter the crumbled feta in a circle around the edge of the pan, leaving the center empty (large enough to fit the yolk of the egg).
1/3 cup crumbled feta
Sprinkle the red pepper flakes over the feta.
1/8 tsp red pepper flakes
Cook until you see and hear the feta sizzling, and starting to melt. This will take a couple of minutes
Place the egg over the feta, being careful to place the yolk in the centre of the pan.
1 large egg
Season with salt and pepper to taste.
salt and pepper
Cook until the egg is to your liking. After a minute or two you can add a lid to the frying pan to more easily cook the yolk. You can also flip the egg and feta, but this can get a little messy.
Place over toast or enjoy as is!
1 piece of toast, your choice
Notes
The crumbled feta is an estimate. You can add more or less to your liking.
