I have Crate & Barrel's white square bowls (to go with my square set), but they are only 6". Sorry to hear they chipped.
I did some poking around on WS's site. There are a few you might check out, i.e. the chili bowls & Tunisian bowls.
Just as an example - There use to be a Mikasa outlet in my area, if you broke a dish or wanted to add some serving pieces. Depending on the manufacturer, w a little reaserch, you might be able to find some match-y pieces. for the set you like/have.
Pier 1 or Cost Plus may have what you're looking for. (I like the bowls that say "Pasta" inside.)
I have the oriental bowls, but they are small - soup serving size.
Here's a link to Mikasa. (The Italian Countryside w matching tureen looks pretty, & large.)
