Toast sourdough until deeply golden, not pale, not burnt. You want structural integrity. A pale toast buckles under the toppings.
While bread toasts, halve and pit the avocado. Scoop flesh directly onto the hot toast.
Smash roughly with a fork, 4–5 presses max. Season immediately with flaky salt, cracked pepper, and lemon zest while it's warm.
Cook your egg using whichever method you prefer. The fried egg takes the same time as the toast, run them simultaneously.
Lay the egg on top of the smashed avocado. Don't center it perfectly, slightly off-center looks more natural and honestly more appetizing.
Scatter pickled onions, crumbled feta, and red pepper flakes over everything.
Finish with a tiny extra pinch of flaky salt on the egg yolk specifically. It makes a difference.
Eat immediately, avocado toast waits for nobody.
