Recipe Information
Ingredients
- 4 large leaves romaine lettuce leaves
- 1 ripe avocado
- 1 tablespoon lemon juice
- 0.25 teaspoon sea salt
- 0.25 teaspoon black pepper
- 1 small cucumber
- 1 medium tomato
- 0.5 small red onion
- 1 medium carrot
- 1 medium bell pepper
Instructions
Start by preparing the avocado spread. Cut the avocado in half, remove the pit, and scoop the flesh into a small mixing bowl.
Add lemon juice, sea salt, and black pepper to the avocado. Mash everything together until smooth and well-mixed. Set aside.
Rinse and dry the romaine lettuce leaves carefully; these will serve as your bread replacement.
Wash and thinly slice the cucumber into rounds.
Core the tomato and slice it into thin, even slices.
Peel and thinly slice the red onion.
Peel and shred the carrot using a grater or slice it thinly into matchsticks.
Wash and slice the bell pepper into thin strips.
To assemble the sandwich, lay two romaine lettuce leaves flat for each sandwich.
Spread a generous amount of the avocado mixture onto each lettuce leaf.
Layer the cucumber slices, tomato slices, red onion, shredded carrot, and bell pepper onto the leaves evenly.
Top with another lettuce leaf to close each sandwich.
Serve immediately to enjoy the freshness of the ingredients. Optionally, use an extra sheet of parchment paper or kitchen twine to keep the sandwiches neatly wrapped.
