Serve this speedy sauce with simply prepared chicken, pork, or fish.
In a medium bowl, whisk lime juice and honey until combined. Season with salt and pepper; set aside.
Slice off both ends of each orange. Following the curve of the fruit, slice away peel and white pith. Cut oranges into quarters lengthwise; slice sections crosswise into 1/4-inch thick pieces. Transfer to bowl along with onion and avocado; toss gently to coat with dressing. Spoon over chicken breasts (or fish or roasted pork). Serve immediately.
To dice an avocado: After removing the pit, use the tip of a paring knife to cut avocado into cubes, without slicing through the skin. Then, cupping avocado, scoop out with a large spoon.
