Mix chicken, cream cheese, chives, milk, and salt in a medium bowl
(mixing with hands works best) to make filling, and store in a 1 qt
freezer bag. Put crouton crumbs in another 1 qt bag, attach it to
bag of chicken filling, and freeze them. Refrigerate crescent rolls.
To prepare for serving, thaw chicken mixture. Unroll crescent
rolls. Each tube will contain 4 rectangles of dough with a diagonal
perforation. Press dough along each perforation so the rectangle
halves will not separate. Place about 1/4 cup of chicken mixture
into the center of each rectangle. Fold dough over the filling, and
pinch the edges to seal tightly. Dip each packet in melted
margarine, and coat with crouton crumbs. Place packets on a baking
sheet. Bake in a preheated 350 F oven for 20 minutes or until
golden brown. Packets are good either hot or cold.
