Bring a pot of salted water to a boil and prepare a bowl of ice water. Add the green beans to the boiling water and cook until still very crisp, 1 to 2 minutes, then transfer to the ice water until cool. Cut in half.
Whisk together the oil, honey, mustard, vinegar and garlic in a large bowl. Season lightly with salt and pepper. Add the green beans, lima beans, kidney beans, white beans, almonds, cranberries and scallions and toss until everything is coated. Season to taste. Sprinkle with cilantro. Serve immediately or cover and refrigerate until ready to serve, up to 1 day.
