Frikadeller is an incredibly common meal in Denmark, so it is eaten very frequently. It is normally eaten as a main course at dinner, as an appetizer (my favorite), or even on smørrebrød during lunch with some potato salad. If eaten on smørrebrød, the Frikadeller would be served as an open faced sandwich on a slice of toasted rye bread and a side of pickled cucumbers or sour cabbage.  You can eat frikadeller either warm or cold.
