In a bowl, drizzle 15 ml (1 tbsp.) olive oil over bread cubes and mix. Season with salt and pepper. Place on the other baking sheet and cook in the oven for 6 to 8 minutes or until croutons are nice and golden. Set aside.
In a bowl, mix Dijon mustard, lemon juice, and honey. Season with salt and pepper. Whisk in olive oil in a steady stream. Set aside.
In a large bowl, combine beans, tomatoes, parsley, arugula, and croutons. Toss gently with a few spoonfuls of vinaigrette.
