Smoked mackerel flaked onto toasted sourdough with a tangy pink pickled onion, lemon, and cracked pepper. Cheap, oily-fish rich, feels genuinely like a meal.
Oily fish delivers omega-3s and a big protein hit from a shelf-stable tin — useful when cooking feels like too much effort. The acidity of the pickled onion helps cut through the richness, which can otherwise feel heavy on queasy mornings.

Spring-water mackerel has a cleaner taste than oil-packed for breakfast. Press the flakes lightly into the toast so they don't roll off with the first bite.
Use gluten-free sourdough for coeliac, or swap mackerel for 100g smashed butter beans for a vegetarian version.
