Spoon dressed salad onto each leaf. Sprinkle with parmesan (if using) and serve.
The filling for the lettuce cups can be dressed ahead of time to make assembly even easier.
Omit the parmesan and egg in these lettuce cups. Want to swap a protein? Mashed chickpeas are a good substitution.
Add leftover chicken, turkey, or steak to these lettuce cups if you desire.
Any other vegetables can be added to the salad filling for these lettuce cups. Get creative!
