Take the slowcooker and add the onion, chicken, wine, lemon juice, olive oil, parsley, salt, pepper ad thyme
Cook it on the low setting for about 5 to 6 hours or until the chicken is tender and falling apart
Turn the cooker to high and add the orzo in. Stir through and cook on high until the orzo has absorbed most of the liquid that is already in the slowcooker. Start by adding hot water, starting with 1/2 cup and after that 1/4 cups at the time or as needed for the pasta to cook through.
The total cooking time for the pasta will be around 25-35 minutes so much longer than regular pasta cooking times. Turn the slow cooker off when the orzo is al dente and the consistency is quite wet and sloppy looking. The pasta will continue to absorb liquid as it rests.
