Fregola is a semolina pasta with a texture somewhat akin to that of couscous - don't overcook it or it will become soggy. If you can't find fregola, a short pasta such as risoni or a grain such as freekah will work well.
Note Fregola is available from select delicatessens and Italian grocers. Chevrette is a semi-hard cheese available from select delicatessens. If unavailable, substitute another semi-hard goat's milk cheese.
