I spend time cooking for the family and then eat the leftovers for lunch. Just like a lot of swedes do. Make a dinner that works in the microwave for lunch and you are all set. No time wasted on going to the restaurant and waiting for food. More time to talk over the lunchtable in peace. Maybe even switching lunch with a coworker.

See I eat lunch out so I can use those leftovers for dinner the next day. Gives me and my girlfriend more time to spend together or on our hobbies if we only have to cook every other night.
