Lasagna has always been closely tied to Christmas for me. Growing up in an Italian family with five children who were not enamored of fish, it became our family's traditional Christmas Eve dinner. I was surprised to learn that National Lasagna Day was celebrated at the end of July- on my English-German mother-in-law's birthday, no less. While making lasagna would be a great way to celebrate, it's a bit too hot for turning on the oven these days. Luckily, there are several restaurants that are offering half price lasagna to celebrate. Buca di Beppo is even serving up free lasagna.
