In a small bowl, stir together the teriyaki sauce, honey, and butter.
Fill a bowl with cold water and ice cubes.
Bring a large pot of water to a boil and add the lemon juice. Drop in the beans and cook for 4 to 5 minutes, or until beans are bright green. Drain the beans in a colander and then plunge them into the iced water. Drain again and set aside.
In a skillet, cook the bacon until very crispy, crumble and set aside. Saute the bell pepper and onion in the hot bacon fat for 2 minutes. Add the beans, cashews, and bacon to the skillet. Add the teriyaki-honey sauce and toss gently.
