This lemon chicken orzo soup is just what the doctor ordered for those cold, winter afternoons. Add a tossed green salad or hunk of warm, homemade bread and settle into a spot by the fireplace. A rotisserie chicken is a great solution when needing a quick and easy dinner, and one will also work well in this soup, making the prep time even shorter. If using pre-cooked chicken, add 3 cups towards the end of the recipe while the orzo cooks. This will give the chicken time to heat thoroughly.
