Over high heat, bring a large pot of water to a boil. Add beans and cook for 4 to 5 minutes or until tender-crisp. Drain beans and place them in a large bowl of ice cold water for a minute or so.
Meanwhile, in a large skillet, cook almonds over medium heat until golden and fragrant, stirring frequently, about 5 minutes. Transfer toasted almonds to a small bowl.
Stir in thin strips of red peppers, garlic, green beans, salt and black pepper; cook, stirring occasionally, until peppers are tender-crisp and beans are hot, about 4 to 5 minutes.
