What’s not to like about a roast beef sandwich? In true Danish tradition, this one is served open-faced, but it’s the added golden brown crispy-fried onions that make this sandwich unusually delicious (and require a knife and fork to eat). It’s been a favorite of mine since I was a kid, and I still love it when my mom makes her smorgasbord luncheon, because this sandwich is always on the menu.

Cooks' Note

For a bit more flavor, add a little horseradish to the Mayonnaise.
