Bring a large pot of water to a boil over high heat. Cook pasta according to package directions, adding beans during the last 2 minutes of cooking. Drain and rinse with cold water until no longer hot. Set aside.
In a large nonstick skillet, cook bacon over medium heat until crisp. Using a slotted spoon, remove bacon from skillet and drain on paper towels. Increase heat to medium-high. Add bread and garlic to hot bacon fat. Stir frequently until golden brown and crispy. Remove from skillet, and let cool completely. Discard garlic.
In a large bowl, combine cooked pasta and haricots verts, cooked bacon, bread, chicken, and next 3 ingredients.
In a small bowl, whisk together vinegar and remaining ingredients. Pour dressing over pasta mixture, tossing to combine. Refrigerate until ready to serve.
