1. Prepare the Sourdough Toast: Place your sourdough bread slices in a toaster or under the broiler. Toast until they are golden brown and crispy to your liking. Keep an eye on them to prevent burning.

2. Cook the Eggs: While the bread is toasting, heat a non-stick skillet over medium heat. Add olive oil or butter. Once shimmering, crack the eggs into the pan. Cook for 2-3 minutes, or until the whites are set but the yolks are still runny (for sunny side up). Season immediately with a pinch of salt and pepper.

3. Mash the Avocado: As the eggs cook, cut the ripe avocado in half, remove the pit, and scoop the flesh into a small bowl. Add the remaining salt and pepper. Use a fork to mash the avocado to your desired consistency – some prefer it smooth, while others like it a bit chunky.

4. Assemble the Toast: Once the sourdough is perfectly toasted, spread the mashed avocado evenly over each slice. Don’t be shy; a generous layer is key to a satisfying experience.

5. Top with Eggs: Carefully slide one sunny side up egg onto each avocado-covered toast slice. Ensure the yolk is still intact and ready to burst.

6. Add the Finishing Touches: Sprinkle the mixed seeds generously over the eggs and avocado. If using, add a pinch of red pepper flakes for a little heat or fresh chives for an herbaceous note. Serve immediately to enjoy the warmth of the toast and the runny yolk.
