I am in a CSA, with a box of vegetables from the farm weekly, enough for two people.
The Introverted Thinker could polish off much more than a "two people" supply because she is happiest swimming 3-5 miles six days a week. But she is GONE to college. Darn it.
I have an ancient dehydrator that was my grandmothers and that is basically a box with four screen drawers and a light bulb. I am drying apples, Wolf River, and can't keep up. SLICE MORE. Not being able to keep up is much better than being hungry.
When the Introverted Thinker was home, I would make dinners "for six" according to the recipe. We might have some left over but not enough for another dinner. I was still not perfect at using all the vegetables but that was more being tired of cooking than not having the capacity to eat it all. We would ignore the vegetables guilt tripping us in the refrigerator and sneak out for a slice of pizza some nights.
Now I have to learn to cook for just me. Change and change and change again.
