Directions:

Add chicken breasts after adding oil to your pan; sprinkle with 1/4 teaspoon salt (optional). Cook 5 minutes. Reduce heat to medium; turn chicken over and cook 5 - 7 minutes longer or until juices run clear when thickest part of breast is pierced.

While chicken cooks, from 1 orange, zest 1/2 teaspoon peel. Squeeze 1/2 cup juice into 2-cup liquid measuring cup or bowl. Cut off any peel and white pith from second orange. Holding orange over same liquid measure to catch juice, cut on either side of membranes to release each section, allowing fruit and juice to drop into cup. Squeeze membrane to release any excess juice. You should have at least 3/4 cup orange juice and sections. Stir in marmalade, vinegar, cornstarch, orange peel, and 1/4 teaspoon salt.
Add garlic to drippings in skillet & 1/4 teaspoon orange zest; cook 15 seconds, stirring. Add orange-juice mixture; heat to boiling. Boil 3 minutes or until sauce thickens very slightly. Return chicken with any juices to skillet; heat through, turning to coat every 2 min with sauce. Then cook to your liking!

Enjoy!
