So I recently cleaned out our fridge and was disgusted at the amount of rotten/food that had gone bad that I threw out.  
I'm living with a roommate and we both seem to have the same problem of forgetting about things in the fridge and then food goes to watste.  
 
I need ideas on how to change this! Because that wasted food is going to add up $$$!  
 
And on a side note, I find it very difficult to cook for only 1 or 2 people. Does anyone have any good meal ideas for 1 or 2 people?!  
 
Thanks in advance for your help!
