Ham and Cheese Puffs

I like poppable foods--things you can just pop in your mouth. These things fit the bill and are a nice change from the usual things I can eat.

Ham and Cheese Puffs
1 (2.5 ounce) package sliced fully cooked ham, chopped
1 small onion, chopped
1/2 c shredded Swiss cheese
1 egg
1 (8 ounce) package refrigerated crescent rolls

Combine the first 4 ingredients, set aside. Divide crescent dough into 24 portions. Press into greased mini muffin cups. Spoon 1 tablespoon of ham mixture into each cup. Bake at 350 for 13-15 or until golden brown.

NOTE: I didn't have a mini muffin tin, so I used a regular one, and it was fine. Just divide the dough into 12 and not 24. :)
