Today's recipe read: Combine the remaining 1/2 cup walnuts, parsley, garlic, salt, and pepper in a food processor. Process until the nuts are ground. With the motor running, gradually add oil through the feed tube. Add Parmesan and pulse until mixed in. Scrape the pesto into a large bowl. Add chicken.
.... he added the chicken (cooked, thank God) to the food processor and processed it until it was.... grains.
