In a medium size mixing bowl using an electric mixer, cream together the cream cheese, mayonnaise, Parmesan and seasonings.
Mix in the spinach and green onion by hand mixing until fully blended. Add 1 cup cheddar cheese. Mix well
Roll out the crescent rolls into a 16 x 14 inch rectangle. Press the perforations together.
Spread the spinach mixture from edge to edge. Sprinkle with bacon and remaining 1 cup cheddar cheese.
Begin to roll from the widest edge ending seam side down. Place into the refrigerator for 2 hours or wrap in plastic wrap and chill overnight. (Tip: Don't skip this step. Chilling allows the cream cheese to firm and the pinwheels to slice more easily)
To bake: Preheat the oven to 375°F. Line a large baking sheet with parchment.
Use a sharp knife to cut into 16 even pieces. Place 2-inches apart on pan.
Bake for 20 minutes or until golden. Serve warm.
