Another new chain serving healthy lunches is Vital Ingredient @VitalSaladBar. I stopped off at the Oxford Circus branch on my way back from Biolab, our new venue for one to one consultations in the West End, and had a delicious Butternut, Lentil and Spinach stew with brown rice. Lovely and warming on a cold day, and it kept me full until dinner 6 hours later.
They have an extensive salad bar where you pick and mix your protein, salad and dressings, and a wide variety of healthy snacks and light meals. Check out their web site at www.vitalingredient.co.uk to find your nearest branch.
