In a large bowl, combine shaved Brussels sprouts, bacon, cheese and crushed croutons. Set aside.
Add all dressing ingredients to a small blender and blend until smooth. (You can also whisk all ingredients in a small bowl if you don't have a blender.)
Pour dressing over salad ingredients and toss. Taste for seasoning and add salt and/or more freshly cracked black pepper if needed. Serve.

Notes
*You can purchase Brussels sprouts already shaved, but if you buy whole Brussels sprouts, it's super easy to shred them in a food processor using the slicing blade. Alternatively, you can do this by hand using the slicing side of a box grater. **If you are allergic to anchovies, you can leave these out of the recipe, but be sure to add salt (to taste). Anchovies have a high salt content, which is why I left salt out of the dressing ingredients. If you think you won't like the taste, don't worry - you can't even tell they're in there. They just give this dressing the essential umami, salty flavoring.
