Peppery and zingy, arugula is like watercress with attitude. It makes an attention-getting salad on its own, but you can tone it down by mixing it with milder lettuces. Or, if it's too spicy for you, just sauté it into submission. Please note: Arugula is grown in sandy black soil. Since we try to handle your veggies as little as possible, we recommend you carefully wash your produce a couple of times before eating it.
