One of my favorite bagel sammies is cream cheese, sliced tomato and thinly sliced red onion. I usually put that on an everything bagel. it would be great on a pumpernickel one too.For the past 2 weeks, I have been vegetarian just at lunch, so lettuce, tomato, onions, cheese, mayo. I wonder if nuts would taste good on a sandwich? That would add some extra protein. Maybe I'll try it tomorrow.
