Lupin Free Watercress Lemon Sauce
Bright, peppery watercress meets zesty lemon in this vibrant blender sauce that comes together in just minutes. The fresh greens get puréed with garlic, lemon juice, and a little zest before a slow drizzle of extra virgin olive oil pulls everything into a silky, emulsified finish. It's the kind of sauce that makes a simple grilled fish, roasted vegetables, or a bowl of grains feel genuinely special. Because it's built entirely from whole, recognizable ingredients — fresh produce, olive oil, salt, and pepper — there's no need to scan labels for hidden legume-based fillers or flour extenders that can sneak into store-bought condiments. Lupin, a legume increasingly used in sauces and dressings as a thickener or protein booster, has absolutely no place here, and you won't miss it. The optional parsley adds a gentle herbal note, but the watercress alone brings enough personality to carry the whole thing. Make a batch, keep it in the fridge, and reach for it all week long.
