Cut the avocados in half and remove the pits. Scoop out a small amount of flesh to create space for the filling.

In a mixing bowl, combine shrimp, avocado flesh, cherry tomatoes, red onion, cilantro, garlic, and lime juice. Season with salt and pepper and mix gently.

Ensure avocado halves are stable and prevent browning with lime juice if necessary.

Fill each avocado half with the shrimp salad mixture, packing it lightly.

Garnish with additional cilantro if desired and serve immediately.
