Chicken With Sauteed Onions - cooking recipe

Ingredients

1 tablespoon olive oil
2 large sweet onions (about 12 ounces total) or 2 large Spanish onions, thinly sliced and separated into rings (about 12 ounces total)
2 teaspoons sugar or 2 teaspoons Splenda sugar substitute
4 boneless skinless chicken breast halves (about 1 pound)
2 tablespoons stone ground dijon mustard
3/4 teaspoon cracked black peppercorns

Preparation

Heat the oil in a large nonstick skillet. Saute the onions over medium-low heat until tender and golden. Add the sugar after the first 5 minutes of cooking. Caramelizing the onions will take about 15 minutes; stir occasionally. Remove the onions from the skillet with a slotted spatula; set aside.
Brush the chicken on both sides with mustard; sprinkle with pepper. Saute in the same skillet over medium heat, about 5 minutes per side, or until cooked through.
Arrange the reserved onions over the chicken; heat through. Serve with additional cracked pepper, if desired.
