This tuna salad leans on flaked, protein-packed tuna as its base, folded together with crisp celery and sharp red onion for crunch in every bite. A spoonful of Dijon mustard and a bright hit of fresh lemon juice cut through the richness and keep the flavor lively instead of heavy. Fresh parsley adds a little color and a clean, herby finish if you want it. It comes together in minutes with no cooking required, which makes it an easy go-to for meal prep or a quick weekday lunch. High in protein and light on fuss, it's a solid option to build into a PCOS-friendly routine. Pile it on greens, tuck it into lettuce cups, or eat it straight from the bowl — it holds up well in the fridge for a couple of days, so it's ready whenever hunger strikes.
