Raspberry Balsamic Chicken

My mom recently got rid of a few of her cookbooks, and this recipe was in one of the ones I "inherited". I am making it tonight, and already tasted the sauce...it is delish!

Raspberry Balsamic Chicken

1 t olive oil

1/2 c chopped red onion

1/2 t dried basil

1/2 t salt, divided

3-4 chicken breasts

1/3 c seedless raspberry preserves

2 T balsamic vinegar

1/4 t black pepper

Heat olive oil over medium heat on stove until hot. Add onion; saute for 5 minutes. Sprinkle 1/4 t salt and dried basil over chicken. Reduce heat to medium. Add 1/4 t salt, preserves, vinegar and pepper to pan. Stir constantly until preserves melt. Pour sauce over chicken and bake at 350 for 35-45 minutes.
