In a small bowl, whisk together olive oil, parsley and garlic powder; season with salt and pepper, to taste.
Spread bread cubes in a single layer on a baking sheet. Stir in olive oil mixture and gently toss to combine. Place into oven and bake until crisp and golden, about 13-15 minutes; set aside.
For the all-purpose dressing
In a medium bowl, whisk olive oil, vinegar, Dijon, oregano and garlic powder; season with salt and pepper, to taste.
For the salad
To assemble the salad, place romaine in a large bowl; top with tomatoes, cucumbers, carrot, onion, almonds, Parmesan and croutons. Pour half the dressing on top of the salad and gently toss to combine. Serve with remaining dressing, if desired.
