In a large skillet, add the sausage over medium-high heat and begin to break down with a spatula, about 2 minutes.
Add shallots and broccoli rabe and continue to break apart the sausage while cooking for about 7 minutes.
Add in the garlic, salt, pepper flakes and wine and cook over medium heat about minutes, breaking down the sausage and cooking the wine down.
Remove from heat and place the sausage mix into a mixing bowl, let it cool for about 10 minutes.
Drain in a colander so there is no extra liquid then transfer to a mixing bowl and mix in the parmesan cheese and mix well.
Assemble the egg rolls: One at a time, place egg roll wrapper on a clean surface, points facing top and bottom like a diamond. Spoon 1/4 cup sausage mixture onto the bottom third of the wrapper.
Dip your finger in a small bowl of water and run it along the edges of the wrapper. Lift the bottom point nearest you and wrap it around the filling. Fold the left and right corners in toward the center and continue to roll into a tight cylinder.
Set aside and repeat with remaining wrappers and filling.
Air Fryer Method
Spray all sides of the egg rolls with oil using your fingers to evenly coat.
In batches, air fry 370F for 7 minutes, turning halfway through until golden brown. Serve immediately, with marinara sauce on the side, if desired.
Oven Method
To bake, preheat oven to 400F.
Place the rolls on on a greased baking sheet coated with oil spray. Spray each roll evenly with oil.
Bake for 6 to 8 minutes on each side, or until the rolls are crisp and golden brown.
