MIX first 5 ingredients until well blended. Brush 1 phyllo sheet lightly with butter; top with 2 more phyllo sheets, lightly brushing each layer with some of the remaining butter. Place remaining phyllo between sheets of plastic wrap; set aside.
SPREAD 1/5 of the spinach mixture along one short side of phyllo stack. Fold in long sides of phyllo; roll up from one short side to make log. Repeat with remaining phyllo sheets and spinach mixture. Brush with remaining butter. Make small cuts in tops of logs at 1-inch intervals. Place in large freezer-weight resealable plastic bags or wrap tightly in plastic wrap.
FREEZE up to 3 months. When ready to bake, remove desired number of logs from freezer. Refrigerate, tightly wrapped, several hours or overnight until thawed. Unwrap, then place on baking sheet. Bake in 375°F oven for 25 min. or until golden brown. Cool 5 min. Transfer to cutting board. Use serrated knife to cut each log into 6 slices.
KRAFT kitchens tips:
Leftover phyllo sheets can be wrapped tightly and refrozen.
HOW TO PREPARE WITH 18X14-INCH PHYLLO SHEETS
Use a total of 9 phyllo sheets, spreading 1/3 of the filling on each stack of 3 sheets and rolling up each stack to make a total of 3 logs. Freeze and bake as directed. Cut each log into 10 slices to serve.
Omit butter. Spray phyllo sheets with cooking spray instead of brushing with the melted butter.
