A couple of years ago I was at my friend Amanda’s house helping make Friendsgiving dinner. (In this scenario, “helping” means standing near her and drinking Malbec.)  We’re chatting while she’s dicing veggies, shredding cheese, stuffing mushrooms, and browning elk sausage.  And it dawns on me- she’s not running to the trash can every 30 seconds to toss scraps as she cooks, yet there are no piles.  Where is everything going?  I know I saw her crack some eggs.  Answer: the scrap bowl.  Amanda tosses butter wrappers, empty cans, veggie ends and eggshells into a bowl as she cooks, greatly reducing the number of steps she has to take per meal…
