I am as lapsed a Catholic as you'll ever meet. But I forego meat on Fridays during Lent. Old habits die hard. I don't otherwise fast during Lent but my brother, another lapsed Catholic, still does (he's giving up beer this year).
During Lent (Cuaresma) here in Mexico, many local women sell capriotada on Fridays. They just put a handwritten sign on their doors late in the week announcing the sale. Capriotada is a bread pudding, that contains both sweet and savory elements. It has the requisite bread, cinnamon, cloves, raisins and sugar (very sweet piloncillo, an unrefined cane sugar sold in cylindrical shapes). Instead of eggs and milk as a binder, only water is added. There is always a ton of cheese in it which becomes the binder. Many senoras add tomato and onion; it varies household to household. Nuts are sometimes found in it, too.
While I buy a piece every Friday on our walk home from dinner, I have not acquired an appreciation of it.
