A light and refreshing substitute for rice!
Stir the broth, lemon juice, lemon zest, butter, and salt together in a big saucepan and get the whole thing boiling. Add the couscous to the liquid and stir it around to get an even coat. Put a cover on the pan and remove it from heat. Let the couscous soak in the liquid until the moisture is mostly absorbed, about 5 minutes.
Use a fork to fluff the couscous a bit, then stir in pimento peppers, pine nuts, and parsley.
