Sorry no cooking teaching reccos from me either, and it might be a little more challenging there than in Bologna or Amalfi Coast, where I have seen cookery schools.
I reckon you did the best thing though - ask the host. If anyone would know of someone suitable, amateur or it's their business, that ought to be the best attempt to find them.
If that doesn't get any options, there's no reason not to raid the excellent local specialist food shops, something I enjoy doing rather too much. We find the following super-easy, but have cooked properly in the past
- Fresh pasta from a local pastificio. We've yet to find a bad one. Add some butter and fresh herbs once cooked and drained, and that's often enough.
- Gastronomia prepared foods. Some Alimentari also have similar fresh prepared foods, but not all. Generally they can either be eaten cold or reheated.
- Rotating salad / picnic / supper. Getting a mix of whatever looks tasty, and each day have a meal (or two) from it, topping it up with other stuff to keep it interesting. Cheese & cured meats, or eggs can also double up for breakfast, though ideally we get fresh fruit in and grab some yoghurts for that.
I must admit that with a wood fired oven, I might be tempted to make pizza / fresh bread.
One easy and local recipe, is to raid that place with the pears, and also grab a bottle of moscato d'asti wine. Peel the pairs and poach in the wine (in as narrow a saucepan as they have), along with some cinnamon (and other cooking spices if there are any). No additional sugar needed as the wine is sweet, but add some if you prefer it sweeter. 45 mins for the pears, but you can take them out and blast the liquid for a few more minutes to make it more syrupy. If there's enough wine left in the bottle, a chilled glass each should be good.
