In the beginning, there was Bruegger’s. Prior to Bruegger’s, I have vague recollections of Lucky Charms, eggs, or, on rare occasions, stacks of pancakes. The recollections are vague because I was very young but also because bagels came in like a blitzkrieg and annihilated all other breakfasts in one fell swoop. Once Bruegger’s opened up in West Concord it was all over. The Tzelnics have been a bagel family ever since.
