Breakfast was the first meal, unfortunately. Dinner was served around 3-4 hours before landing if I remember correctly. During the flight, as usual on daytime atlantic flights (unfortunately), they dimmed all the windows to simulate a night. I napped for maybe 2 hours, then got up and asked the flight attendant for a coffee and some cookies. She asked me if I wanted a sandwich and cake instead. It was a combo apparantly as it was sealed in plastic together. Was just a small cheese sandwich and a dryish chocolate cake but it was sufficient as a mid-flight snack together with the coffee. They also distributed tiny cards that listed additional snacks like nuts, dried fruits etc but the only "semi-substantial" stuff was the cheese roll + cake combo.
