No cooking for one month

I decided that during the last month of my thesis writing, I won't
cook for meals.
It is because I wanna save time for study.
Now it is already about 20 days. My meals are sandwich,
sandwich,Turkish pizza and Italian pizza.
Haven't eaten rice for a long time.
From now I still can afford it. However, I do desired for better food.
It seems like the canteen in my office provides me better food now. It is
also my only chance to eat something which is not sandwich or fast
food now.
