Then someone has to remember to buy them and take out the trash. The canonical solution is for you and your lazy roommates to eat straight from the pot over the sink. When done, fill the pot with water, to discourage the ants and roaches. Occasionally, you end up with a drowned ratling, but hey, wachagonna do?
One pot, no dishes. Each roommate has to keep track of their private spoon. Greedy "clever" roommate who shows up with a liter ladle triggers a spoon fight in the kitchen. Eating from pot by hand is corrected by rapping their knuckles with your spoons. Eventually, all the glassware ends up broken, and some bozo threw out all the used red solo cups, but luckily, the kitchen faucet has a spray attachment.
“Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.”
― Antoine de Saint-Exupéry, Airman's Odyssey
If you're going to optimize that, move over to Soylent or Huel. Instead of preparing food and eating it, it's more efficient to mix powder with water, and for people to drink the resulting slurry. As long as that mix has all the things a body needs, you're all set. No mess!
