Changes: Used 2 large chicken breasts rather than 4 small (which increased the cooking time). I had yellow onions, not red onions, so that is what I used. I added (unmeasured) basil, oregano, and black pepper to the tomatoes.
Thoughts: The balsamic vinaigrette gave the chicken a nice tang. This is a simple, tasty weeknight recipe.
