As you all have seen, Italian food here has been amazing...we've eaten a large variety of regional foods with different families. But we don't eat with a family every night, so I've had the opportunity to cook a little at our flat.
The pastor's wife here, Cristina, has taken me to several different shops each week. Here's a sampling of my selections on a normal trip.
scamorza cheese €2.5
fresh mozzarella €1.5
fresh pasta €2
fresh ravioli €2
can of tomatoes €.7
Italian grocery stores look pretty similar to the US. But what I love about shopping in Italy is that even the chain grocery stores have really great delis and bakeries...the best! So you can be confident buying meats, cheeses and breads. Also, the eggs are all fresh and local. My parents' have egg-laying chickens, and these eggs looked just like them -- chicken crap covered, none the same shape or size.
I tried to get produce more from the market than the grocery store, but we weren't around on the first two Tuesdays - which is the only day its open.
There was a local bakery, about a 3 minute walk from our flat, so some days I would walk over there in the morning and make a few selections for the next few days. Usually two normal sized loaves or rolls would cost € .75
For milk, we went to a local latteria (latte = milk) and purchased fresh, local milk in refillable liter bottles. It was so strong and rich. YUM. €1
In all, we spent about €20 ($30 or so) a week on groceries for breakfast, lunch and about 2 dinners.
