Nutty Onion Green Beans

½ pound fresh green beans
1 small red onion, sliced and separated into rings
1/3 c. chopped pecans
3 Tbsp butter
2 Tbsp brown sugar
2 Tbsp orange juice
1 Tbsp Dijon mustard
½ tsp salt

Place beans in a saucepan and cover with water. Bring to a boil. Cook uncovered, for 8-10 minutes until crisp-tender. Drain and set aside. In a skillet, cook onion and nuts in butter until onion is tender. In a small bowl combine the brown sugar, orange juice, mustard and salt. Stir into the onion mixture. Cook 2-3 minutes longer or until sauce begins to thicken. Stir in beans and heat through.
