I get that if you're living in a culvert, there's more to eating well (or at all) than just knowing how to cook.
But then an increase in the cost of cauliflower probably isn't your primary issue either.
If we remove the culvert-dwellers from the equation for a moment, I think there are still plenty of people who have access to a stove or an oven or a hotplate who could probably cook better and cheaper if they could cook at all. And I'm not talking about laying up 100 quarts of tomato sauce here. I'm just talking about rice and dhal versus Mama Michelina's.
