For the frico chips: Place an oven rack in the center of the oven. Preheat the oven to 375 degrees F.
Line a baking sheet with a silicon mat. Place eight 1-tablespoon mounds of cheese on the mat and gently tap down until flat. Bake until golden and bubbly, 8 to 10 minutes. Let the frico chips cool until firm, about 5 minutes.
Place a grill pan over medium-high heat or preheat a gas or charcoal grill.
For the courgette: Using a pastry brush, brush the courgette halves with the oil and season with the salt. Grill until tender, 4 to 5 minutes each side. When cool enough to handle, cut the courgette into 1/2-inch cubes.
For the shrimp: In a medium bowl, mix together the oil, soy sauce, garlic, zest, parsley, chives, salt and pepper. Add the prawns and toss until coated. Refrigerate for 30 minutes. Grill until pink and cooked through, 2 to 3 minutes each side. Chop into 1/2-inch pieces.
For the dressing: In a small bowl, whisk together the oil, lemon juice, agave, mustard, salt and pepper until smooth.
In a medium bowl, combine the courgette, prawns, dressing and avocado. Gently toss until all the ingredients are coated.
Using a slotted spoon, spoon the salad into 8 small ramekins. Garnish with frico chips and serve.
