Heat oven to 375. Gently toss your bread cubes in olive oil and salt on a rimmed metal baking sheet. Space the cubes out so they toast up properly, then bake for 10 to 12 minutes, or until crispy and golden brown. Set aside to cool.
Meanwhile, in a medium bowl, whisk the dressing ingredients until combined.
Gently fold in the beans, tomatoes, cheese, and parsley. Taste, and adjust seasonings if you wish.
Place the greens in your serving bowl, then top with the dressed bean mixture, followed by the croutons. If you don't care about aesthetics, feel free to toss the greens right into the bowl you mixed the dressing.
