Preheat oven to 375°F. Line a sheet pan with parchment paper and set aside.
To make the blackberry sauce, add 1 & ½ cups of thawed Oregon Blackberries and 2 tablespoons of honey to a blender. Blend until smooth and transfer to a small bowl.
Toss arugula in olive oil and season with salt and pepper.
On a lightly floured surface, roll the puff pastry out to a large rectangle about double the original size. Using a pizza cutter or knife, cut dough into squares.
To make the bundles, spread about 1 tablespoon of the blackberry sauce in the middle of the square, followed by a small serving of arugula, a slice of prosciutto, and a serving of goat cheese.
Lift two opposite corners of the puff pastry squares and wrap them around the filling and press to seal. Brush puff pastry with egg wash.
Bake for about 12-15 minutes, or until puff pastry is golden and puffed. Serve immediately. Use any remaining blackberry sauce for dipping & Enjoy!
