Salad with Chicken Breast
Trim and rinse the lettuces, spin dry and tear into bite-size pieces. Cut chicken into bite-size pieces.
Remove the crusts from the bread, cut into cubes and saute on all sides in hot butter; drain on paper towels.
Whisk together the vinegars with the mustard, sugar, and oil and season with a little salt and pepper to taste.
Toss the lettuce with the salad dressing, arrange on plates, top with the chicken and sprinkle with croutons. Shave the Parmesan with a vegetable peeler (or truffle slicer) and sprinkle over the salad.
