A small handful of nuts is an easy snack between meals. Almonds, cashews, walnuts, and pistachios each have their own taste, so a mix keeps the snacking interesting.
Plain nuts are useful in breakfast bowls, salads, and home cooking. Roasted or lightly salted nuts are better when you want a ready snack with tea.
Start with the nuts you already enjoy, then try one new variety. There is no need to buy every type at once.
