Drain the tuna from cans.

In a mixing bowl, combine the drained tuna, diced cucumber, chopped chiles, peas, finely chopped celery, finely chopped onion, and chopped fresh parsley.

Add olive oil, lime juice, and lime rind to the tuna mixture.

Season with salt and ground black pepper to taste.

Mix all the ingredients thoroughly.

Cut the avocados in half.

Carefully remove the avocado flesh from the peel with a spoon, keeping the skin intact to form a bowl.

Spoon the tuna salad mixture into each avocado half.

Serve immediately.
