Prepare an ice bath; set aside. Bring a large pot of water to a boil. Add a large pinch of salt, and the Romano and wax beans. Cook for 5 minutes. Add the haricot verts, and cook until the beans are tender, 5 to 7 minutes more. Drain, and transfer to the ice bath to stop cooking. Drain well; set aside.
In a large skillet over medium heat, heat the oil. Add onions and cook, stirring, until translucent, 3 to 5 minutes. Add stock, and cook until reduced by half. Add the beans, garlic, and butter. Cook until beans are lightly glazed. Add tomato, basil, parsley, lemon, olives, and almonds, and heat through. Season with salt and pepper. Keep warm.
