Preheat oven to 425F. Line two baking sheets with parchment paper or silicone liners.
Roll out the Wewalka puff pastry, and cut it into 8 even rectangles. Using the tip of a knife, gently score all around the edges of the rectangles to create a border. Use a fork and prick all over the inside portion of your rectangles. Repeat with all.
Bake for 15-20 minutes, until puff pastry is flaky and golden brown.
While the pastry bakes, prepare the eggs.
Grab your Hamilton Beach egg cooker, and add the instructed amount of water to the machine for making poached eggs.
I found that lightly greasing the tray worked best for making poached eggs to make sure they did not stick. After greasing, add in 3 Eggland's Best XL eggs to the poaching tray. Cook eggs according to machine directions.
Repeat to make 8 eggs total.
Meanwhile, prepare the avocado. In a small bowl, mash the three ripe avocados with a fork, and season with garlic salt to taste.
When pastry is ready, it's time to assemble! Divide the smashed avocado evenly among the pastry rectangles, then top each square with a poached egg and season with bagel seasoning. Serve immediately!
