Place the cottage cheese in a high-speed blender or food processor and pulse until completely smooth with no remaining curds.
Transfer the blended cottage cheese to a medium mixing bowl.
Fold in the shredded chicken, taco seasoning, diced green chilies, and lime juice until well combined.
Spread the mixture into a microwave-safe serving dish or a small oven-proof skillet.
Top the mixture evenly with the shredded cheddar cheese.
Heat in the microwave for 2 minutes or in a preheated oven at 350°F (175°C) for 10 minutes until the cheese is melted and the dip is warmed through.
Garnish with chopped cilantro and sliced green onions before serving with vegetable crudités or high-protein chips.
