Preheat your oven to 400 degrees Fahrenheit.
Sauté the onion and ground beef together on medium high heat for a couple minutes then add in the garlic powder, Italian seasoning, paprika, salt and pepper. Cook for another 6-8 minutes or until fully cooked.
Line a baking pan with parchment paper.
Cut the puff pastry sheet into 4 equal pieces. Use a fork to poke holes in the middle of each piece leaving a half inch border. Doing this will allow the border to poof up and create a crunchy crust.
Add your beef to where you poked the holes.
Add on your cheese on top of the beef.
Brush your soon to be crust with egg wash.
Sprinkle the edges with some toasted sesame seeds.
Put it in the oven for 17-20 minutes or until golden brown.
Top with sliced avocado.
