Mix ground Ground Sweet Italian Sausage (1.5 pound), Onion (1), Carrot (1), Fresh Baby Spinach (1 cup), Garlic (1 clove), Fresh Rosemary (1 sprig), and Smoked Paprika (1 teaspoon).
Add Salt (1 pinch), Ground Black Pepper (1 pinch), and one of the Egg (1) in a bowl. Mush it together with clean hands thoroughly like you are making meatballs or meatloaf. Set the bowl aside.
Preheat the oven to 400 degrees F (200 degrees C) and line two sheet pans with silicone mats or parchment paper.
Crack the other Egg (1) into a bowl and beat it to make an egg wash. Take the Puff Pastry (3) and lay them out on a clean work surface. Cut them each in half lengthwise to have 6 strips total of puff pastry.
Divide the sausage filling into 6 equal portions. Mold one of the portions into a log down the length of one of the puff pastry strips and repeat with the remaining 5 portions to fill each sausage roll.
Roll each puff pasty sheet tightly to surround the sausage log. Then, brush each roll with egg wash, and sprinkle them with the Black Sesame Seeds (to taste).
Cut each roll into 6 equal pieces to have 36 pieces total. Line 18 pieces up onto each sheet tray. Bake the sausage rolls for 20 minutes.
Reduce the heat to 350 degrees (175 degrees C) and bake them for another 10 minutes.
When they are done, take them out and serve them immediately as a party bite or fun lunch!
Serve and enjoy with Ketchup (to taste).
