Plain pistachios are small, oval nuts with a hard, beige shell and vibrant green kernels, offering a naturally sweet, slightly earthy flavor. They have a satisfying crunch and are typically sold raw or dry-roasted without added salt or seasoning. Packed with protein, fiber, and healthy fats, they support heart health and energy levels. Enjoy them as a simple snack, in trail mixes, or as a nutritious topping for yogurt and salads.
