In a large skillet, brown sausage and onion over medium heat until meat is no longer pink, 4-5 minutes, breaking sausage into crumbles; drain. Stir in chives.
On a lightly floured surface, unroll crescent dough into a long rectangle; seal seams and perforations.
Cut into 48 pieces. Press onto the bottoms and up the sides of greased miniature muffin cups.
Fill each with about 2 teaspoons of sausage mixture. In a large bowl, combine the eggs and cheeses. Spoon 2 teaspoons over sausage mixture in each cup.
Sprinkle with paprika.
Bake at 375° until a knife inserted in the center comes out clean, 20-25 minutes. Cool for 5 minutes before removing from pans to wire racks. If desired, sprinkle with additional minced chives.
