For me, Christmas breakfast is the big work. I'll be cooking two pounds of bacon, biscuits, cinnamon rolls, and ham-and-cheese omelettes for me and the doormen working in the building on the holiday.
Dinner is super low-effort, like frozen pizza low effort. The upside is that this particular frozen pizza is from Shakespeare's Pizza in Columbia, Missouri. It's a national treasure.
None in my family are big on breakfast, so Christmas breakfast is skipped altogether and we compensate during dinner instead. We usually also get a handful of in-laws over as well, so I'm currently "very busy" attending to "work matters" as I am typing this, hoping that people can take the hint and get the fuck out of my kitchen.
If it involves a fresh ham (aka uncured), you would be correct. Although those seem to provide adequate grease sauce, so please excuse my wild speculation.
