Preheat the oven to 325°F and grease a 9 x 9-inch square springform pan. Crush the day-old bread or put it into a food processor to make bread crumbs, then stir together all of the ingredients for the meatloaf. Once everything is combined, transfer the ground beef mixture to the springform pan.
Place 1 slice of cheese (we used goat cheese, but feel free to use whatever kind you'd like) between 2 uncooked lasagna sheets and insert them into the ground beef mixture in a grid-like pattern, dividing the pan into 9 even sections. If the lasagna sheets are taller than the springform pan, trim them so that they cook correctly in the oven.
Press the bottom of a clean shot glass into each section of ground beef to create small wells in the meat.
Stir together the cream cheese, shredded mozzarella, and chopped chives and spoon the mixture into the wells in the ground beef.
Carefully crack 1 egg into each square.
Transfer the springform pan to the oven and bake at 325°F for 1 hour.
