Begin by slicing the avocados in half lengthwise. Carefully remove the pits and, using a spoon, scoop out a bit of the flesh from the center to create extra room for the filling.
In a medium mixing bowl, combine the shredded chicken with the pesto sauce. Mix well until each piece of chicken is luxuriously coated with the vibrant pesto.
Gently fold in the halved cherry tomatoes, fresh lemon juice, and a pinch of salt and pepper to the chicken mixture. Stir delicately to ensure all ingredients are evenly distributed without breaking the tomatoes.
Generously fill each hollowed half of the avocado with the pesto chicken mixture, making sure to pile it high for a delightful presentation.
Sprinkle shredded mozzarella cheese on top of each stuffed avocado half, allowing it to create a cheesy layer over the flavorful filling.
For a deliciously melty finish, place the stuffed avocados under a broiler for about 2-3 minutes. Watch them closely, as you're aiming for the cheese to melt and bubble without burning.
Once the cheese is perfectly melted, carefully remove the avocados from the oven. Allow them to cool slightly and garnish with fresh basil leaves for a burst of color and flavor before serving.
Notes
Serve on a bed of mixed greens for added texture and drizzle with extra pesto for presentation.
