The so-called Kiwi burger is popular in New Zealand. It's a beef burger topped with cheese, beets, pineapple, onion, tomato, lettuce and a fried egg. This healthier version is bunless, uses chicken, and skips the fried egg.
To make marinade: In a medium bowl, whisk together orange, lime and lemon juices; chipotle chili powder; cumin; garlic; salt and pepper. Place chicken breasts in marinade and refrigerate for at least an hour.
Preheat grill to medium. Brush grill with olive oil and cook chicken for eight minutes on first side (discard marinade). Turn over and cook another five minutes until cooked through.
While chicken is cooking, grill onion and pineapple on oiled grill for four minutes each side.
To assemble, slice chicken breasts in half horizontally and put one breast half on each of four plates. Top each with a slice of tomato, pineapple, onion and cheddar, two beet slices and some sprouts.
