Another really simple one, but it's too delicious not to share.
I wasn't sure if the balsamic vinegar would work well with the cilantro, but it turned out to be a great combo.
Chop the tomatoes into quarts, the salad coarsely, the red onion finely, the avocado coarsely, the cilantro finely. Mix with salt, lots of freshly ground black pepper, EVOO and a healthy splash of balsamic vinegar.
Fry the chicken breast in olive oil, baste in butter, then chop up into bite-size bits and add to the salad. Simple as that.
