Your roommate is hungry and wants to know what's for dinner. You have decided to try and reduce your food waste, so you suggest:
a. going to the store to buy something different than you had yesterday, for dietary variety.
b. making sandwiches with the bread, spinach, and turkey you bought a few days ago.
c. eating out at a vegetarian restaurant.
d. walking to the store to see what is on sale at a discount today.
e. peeling the potatoes before cooking them.
