Howdy, I'm living by myself and need some help in finding what groceries to purchase and how to consume them entirely. For example, I made a stew out of a 3.5lb roast. This can last me a couple of days. I used half a large onion, a few sticks of celery and a couple of carrots. The unused portions of my veggies typically go to waste. I can't spend a great deal of time cooking because I have to clean and well... take care of life things like laundry and such. I'm looking for advice anyone has to offer to help me maintain my pantry and fridge. I know restaurants and large families can easily finish a head of lettuce, I however can't seem to.
