What should we have for dinner?

After a long (more often), hard (sometimes) day at work, all one wants is to reach home and find a hot, delicious meal ready :)
Only if wishes were horses and all that...so the perennial question always remains - "What should we have for dinner"- this more often than not elicits instant groans or silence (depending on what kind of a reaction you tend towards!)....and before one starts envisioning a 4 course meal, even a simple (yet interesting meal) option is so difficult to find and more importantly to think of...

Haven't we worked our brains enough for the day in the office for us to come back and work them again for a menu...
Searching the Internet will always somehow yield results which will require items you don't have just at that moment...can technology not help with a simple invention which would automatically scan what items are available at home and prepare a menu? The rest one can take care of...

Well till some brilliant scientist figures that one out, tell me what are you having for dinner, I might be able to pick up some clues from there...if not for today then some other day...
