Spray a 7-inch heatproof pan, and place the spinach in an even layer at the bottom.
Spray both sides of the scallops with vegetable oil, sprinkle a little more salt and pepper on them, and place scallops in the pan on top of the spinach.
In a small bowl, mix together the cream, tomato paste, basil, garlic, salt and pepper and pour over the spinach and scallops.
Set the airfryer to 350F for 10 minutes until the scallops are cooked through to an internal temperature of 135F and the sauce is hot and bubbling. Serve immediately.
