Make the Dressing
In a medium bowl, whisk together avocado mayo, Dijon, apple cider vinegar, and almond milk until smooth and emulsified.
Stir in parmesan, garlic, Worcestershire (if using), salt, and pepper.
For a thicker, more clingy texture, sprinkle in xanthan gum and whisk or blend briefly.
Cover and refrigerate for 30 minutes (optional but ideal) to allow flavors to meld.
Prepare the Crumble
In a dry nonstick pan over medium-low heat, combine grated parmesan, almond flour, and a pinch of garlic powder.
Toast until golden and lightly crisped (2–3 minutes), stirring frequently. Let cool and crumble by hand.
Assemble the Salad
Toss chopped romaine with olive oil if using.
Add 2–3 tbsp of Caesar dressing per serving, toss to coat.
Top with shaved parmesan and sprinkle generously with the Parmesan almond crumble for texture and flavor.
