How to Easily Fill the Pasta Shells
Spoon cottage cheese mixture into freezer-weight resealable plastic bag. Cut piece off one bottom corner of bag; use to pipe cottage cheese mixture into the drained shells.
Casserole may be assembled ahead of time. Refrigerate up to 24 hours before baking as directed, increasing the baking time to 40 to 45 min. or until heated through before topping with the cheese.
