In the dressing, honey balances the lime's acidity and the chipotle's spice. Add juices from the seared steak to make it even more savory. If you prefer, you can grill the steak instead of searing it in a skillet.
Feel free to use arugula in place of watercress or shrimp instead of chicken in this bright salad. The pineapple-lime dressing is also great spooned over grilled fish or chicken, or simply stirred into rice.
