Make the parmesan crisps (optional). Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper. Spoon small mounds of the grated parmesan onto the baking sheet and flatten slightly to form thin circles. Bake for about 8 minutes, or until golden and crisp around the edges. Remove from the oven and let them cool on the tray (they’ll crisp up as they cool).
Cook your bacon. Air fry the bacon at 400°F (200°C) for 8 to 10 minutes, or until super crispy. You can also pan-fry it over medium heat until crispy if you prefer.
Mix your meatballs. In a large mixing bowl, combine the ground chicken, most of the chopped bacon, ½ cup grated parmesan, ½ cup panko breadcrumbs, ½ cup ricotta, 1 tablespoon fish sauce, 1 tablespoon Dijon mustard, 1 tablespoon miso paste, crushed garlic, chopped basil, lemon zest and a good grind of black pepper. Mix until fully combined.
Roll your meatballs. Wet your hands (this helps prevent sticking), then roll a heaped spoonful of the mixture into a small meatball. Place directly into your air fryer basket or onto a parchment-lined baking sheet if you're using the oven. Repeat with the rest of the mixture.
Cook the meatballs. Air fryer: Cook at 400°F (200°C) for 11 minutes, until golden and cooked through. Oven: Bake at 425°F (220°C) for about 20 minutes, or until golden and fully cooked.
Make the green Caesar sauce. While the meatballs cook, add 1 cup cottage cheese, the flesh of your avocado, 1/2 cup basil leaves, 1 packed cup of spinach leaves, ½ cup grated parmesan cheese, 2 garlic cloves, 1 tablespoon fish sauce, 1 tablespoon Dijon mustard, ½ tablespoon white miso paste, a very good grind of black pepper and 1 tablespoon of olive oil to a food processor or blender. Blend until smooth and creamy. If the sauce is too thick, add a splash of water to help it blend into a silky texture.
Garnish and serve. Spread about three-quarters of the green Caesar sauce on a serving platter. Pile the warm meatballs on top, then break the Parmesan crisps into shards and scatter them over the meatballs. Finish by sprinkling over the reserved bacon and chives. Serve the remaining sauce on the side for dipping.
