I got on a panini kick, last winter, when Austin actually got iced in for 3 days! I didn't use chicken breasts, but deli sliced turkey. I'm always looking for ways to use my fresh rosemary, which I've managed to grow (too successfully!), and I really enjoyed this sandwich! Thanks! Since then, I've made this panini several more times (that overgrown rosemary!), and it's always great. I don't always have tomato, and it's still good. I don't always have gouda, so I've subbed havarti and muenster, and it's still good. I always cook it in my George Foreman, and it's great, for that! I just love this panini!
