Fave pregnancy food?

I'm 18w, and I've had a couple of cravings, I guess. A certain food pops into my head, and I can't stop thinking about it until I get it. Strangely, these craving seem to switch up. One week it's salads, the next it's hotdogs, or maybe a certain candy or junkfood- but then it passes. However, there has been one meal that I seem to have clung to this entire time. No matter how nauseated I may be, it's the only food that I can keep down, and I feel really satisfied after (at least until the next day). I've been completely obsessed with McDonald's sausage McMuffins and hash browns. I've had to start limiting myself to only going once or twice a week. Before I got pregnant, I hated anything to do with McDonald's. Anyone else have that one strange food that has become a go to?
