The classic Greek stew known as giouvetsi (sometimes spelled youvetsi) is a comforting dish of tomatoes, spices, orzo and meat—often lamb or beef. To simplify preparation, our one-pot version calls for boneless, skinless chicken thighs. First we sear them on one side to develop a generous amount of browning, then we simmer the thighs along with the orzo in a warmly spiced tomato sauce seasoned with paprika, allspice and cinnamon. The meat becomes tender and succulent, a wonderful match for the plump, tender pasta. To finish, add a scattering of pleasantly salty, tangy feta cheese.
