The typical Sidh breakfast (or any other meal of the day) is rather bland and Spartan, focused on nutrition rather than taste. A typical morning meal can contain synthetic algae-based nutrient bars with the necessary fibers, vitamins and minerals, a few slices of biotech meat (more often than not substituted by a flavoured synthetic protein paste to go with the bars), a glass of synth-yogurt enriched with genetically-engineered gut bacteria and immuno-boosting nanites, and maybe some fruit juice, which is the only natural part of the meal.
Quite a few of these foodstuffs are engineered specifically for Sidh physiology and metabolism, and would cause quite unpleasant side effects, i.e., stomach cramps and diarrhea, in unaugmented humans.
Ranking Sidhae can afford to eat all-natural foods for breakfast, but usually don't, both because the synthetic substitutes are more efficient at providing for the considerable Sidh nutritional needs, and because habitually doing so could be perceived as excessive luxury by others. Practicality is the primary concern, though - depending on the extent of one's augmentation, a Sidh can require two to five times the daily nutritional intake of an ordinary human in order to power one's many augmentations that grant Sidhae their superhuman strength, resilience and speed. Hence, typical Sidh foodstuffs are engineered for maximum concentration of nutrients rather than palatability.
As some humans have aptly put it, "Sidh food tastes like dog shit with some cat puke, and grows hair on one's chest regardless of sex." While originally referring to the (allegedly) notoriously-unpalatable Imperial military MREs and obviously an exaggeration, it pretty accurately characterizes typical Sidh food as focused on functionality rather than palatability.
