Drain 1 cup cottage cheese for 15 minutes. Preheat the oven to 425 degrees F, line a baking sheet with parchment paper, and brush the paper with olive oil.
Combine the ground chicken, drained cottage cheese, panko, egg, cheddar, jalapenos, green onions, garlic powder, smoked paprika, salt, and black pepper. Mix just until evenly combined.
Shape the chicken mixture into 24 meatballs and arrange them on the prepared baking sheet, leaving space between each one.
Bake the meatballs for 17 to 20 minutes, until browned and cooked to an internal temperature of 165 degrees F. Broil for the final 1 to 2 minutes for a more golden exterior.
Blend the remaining cottage cheese, Greek yogurt, lime juice, garlic powder, and salt until smooth. Stir in the chopped chives after blending.
Rest the meatballs for 5 minutes so their juices settle. Serve them warm with the chilled cottage cheese chive dip.
