1. 1. Prepare the Avocados: Carefully cut each ripe avocado in half lengthwise. Gently remove the pit. Using a spoon, scoop out a small amount of the avocado flesh from the center of each half, creating a slightly larger hollow for the filling. Be careful not to scoop too much, as you still want a good amount of avocado in each bite. Place the scooped-out avocado flesh in a medium mixing bowl.

2. 2. Mash the Avocado Base: Add the lime juice to the scooped avocado flesh in the bowl. Use a fork to lightly mash the avocado, leaving it a bit chunky for texture. The lime juice helps prevent browning and adds a bright, fresh flavor.

3. 3. Combine the Chicken Filling Ingredients: To the bowl with the mashed avocado, add the shredded or diced cooked chicken, buffalo sauce, ranch or blue cheese dressing, finely diced red onion, and chopped fresh cilantro.

4. 4. Mix the Filling Thoroughly: Stir all the ingredients together until they are well combined and the chicken is evenly coated with the buffalo sauce and dressing. Ensure the red onion and cilantro are distributed throughout the mixture. Taste the filling and adjust seasoning with salt and black pepper as needed. If you prefer more heat, add a touch more buffalo sauce.

5. 5. Stuff the Avocado Halves: Spoon the buffalo chicken mixture generously into the hollowed-out avocado halves. Mound the filling slightly to create an appealing presentation.

6. 6. Add Optional Toppings: If using, sprinkle the shredded cheddar cheese over the top of each stuffed avocado. You can also add a few extra cilantro leaves for garnish, or a drizzle of extra ranch dressing.

7. 7. Serve Immediately: Arrange the stuffed avocados on a platter and serve them right away. They are best enjoyed fresh when the avocado is at its creamiest.
