Meet the Cook: As the second oldest of eight children in a busy farm family, I had plenty of opportunity to practice cooking while I was growing up. Now that our three children are grown, I am cooking just for my husband and me - though few weeks pass without visitors. For "country eaters", this hearty pie is perfect! -Diane Gillingham, Carman, Manitoba
