Preheat oven to 400°F and line baking sheet with silicone baking mat or compostable parchment paper.
On a floured surface roll out puff pastry (if not pre-rolled) into a square or rectangle about 12- x 12- inches. Using a pizza cutter or knife trim about 1/2 inch of pastry around edges and fold over the outer edge to create a frame. Place back in the fridge while you prepare the remaining ingredients or waiting for the oven to come to temperature.
With a pastry brush, brush surface and edges of puff pastry lightly with egg wash then with a light coating of Bonne Maman strawberry jam.
Sprinkle with Gruyere and cut asparagus. Season with salt and pepper.
Bake for 15 minutes or until pastry is golden brown and asparagus is tender. Let cool for 5 minutes before adding a handful of fresh microgreens and a drizzle of more jam if desired. Enjoy!
