Heat a small skillet over medium heat. Add the pumpkin seeds (dry, without any oil or butter). Toast for 2-3 minutes, stirring frequently, until they turn golden and start to pop. Watch closely—they can burn fast! Once done, set them aside to cool slightly. Coarsely chop your pumpkin seeds.
Cut the avocado in half, remove the pit, and scoop the flesh into a small bowl. Add the lemon juice and a pinch of flaky sea salt. Mash with a fork until smooth but still slightly chunky—texture is key here. Taste and adjust seasoning if needed.
Pop your sourdough slices into a toaster or heat them in a skillet until golden and crisp on the outside. If you’re using a fresh loaf, cutting it thick gives that perfect balance of crusty and soft.
Spread a generous layer of the mashed avocado over each slice of toasted sourdough. Sprinkle chopped cilantro and the toasted pumpkin seeds evenly on top. Add quartered tomato on top. Finish with an extra pinch of flaky sea salt and a few grinds of black pepper. If you’re feeling adventurous, add a dash of red pepper flakes.
Serve immediately while the bread is still warm and the avocado is fresh. Pair it with a perfectly cooked sunny-side-up egg and some irresistibly crispy bacon strips, and you’ve got a breakfast that’s pure bliss.
