Not everyone's cup of tea but dolphins (or at least one @blue_dolphin 🙃) apparently like fish tacos for breakfast. Edited to add even dolphins can have sensitive stomachs so I deferred this meal to around 9 AM.
From Melissa Clark's Dinner: Changing the Game with a red cabbage, lime and jalapeño slaw, rockfish from the fish delivery I picked up the other day and a yogurt/garlic/lime crema.
