While oven is preheating, prepare green beans by cutting in half and chopping off the stems.
Place green beans (1lb), slivered almonds (1/2c), garlic (2 cloves), olive oil (1 Tblsp), and salt (1/4tsp) on baking sheet and mix.
Cook for 25-30 minutes, until green beans are slightly soft and slivered almonds are slightly browned.
While green beans are cooking, prepare balsamic reduction. Place balsamic vinegar (1/2 c) in a small saucepan and cook over high heat until boiling. Once boiling reduce to medium-low heat and simmer for approximately 12-15 minutes, until balsamic is slightly thick.
Once green beans are done, pour balsamic reduction over them and mix until well covered.
Serve warm as the perfect side to any main dish!
