Parsley

Parsley sits in your fridge looking modest, and that's exactly why people underestimate it. Sniff a bunch before you buy: it should smell green and sharp, almost peppery, not dull or musty. That smell is your best guide, because parsley loses its punch fast once cut — the bright aroma fades, and you'll notice it turn flatter and duller the longer it sits. Look at the stems too. They should snap, not bend. A limp stem means the leaves will wilt before you've even chopped them.

Some people say parsley is just decoration, a garnish you push to the side of the plate. No! Raw parsley, 100 grams of it, gives you 36 kcal, 2.97 grams of protein, 6.33 grams of carbs, and only 0.79 grams of fat. That's a real ingredient, not confetti. Treat it like decoration and you throw away much of the dish's fresh, green flavor — and its nutrition — before the guest even picks up a fork.

Buy it fresh, keep it cold, and use the stems too — they carry flavor, not just the leaves. Chop parsley at the last moment, right before serving, so the aroma stays where it belongs: in the food, not in the air above your cutting board.
