What high-protein lunches usually need
The useful version of this goal is not endless meal-prep machismo. It is having lunches that are satisfying enough to carry the afternoon without turning the plate into a punishment.
Jar lunches, toast lunches and cold plates are easier to repeat than heroic prep routines.
Protein without fibre can still leave lunch oddly unsatisfying.
Miso, herbs, citrus and yogurt do a lot of useful work here.
