Add the cubed paneer, tenderstem broccoli and red onion to an airfryer-safe dish or liner. Toss with the oil, curry powder and a pinch of salt until everything is nicely coated. Airfry at 180°C for 8–10 minutes, shaking or stirring halfway, until the paneer is golden and the broccoli has started to char.
Stir in the curry paste and coconut milk, making sure the paste is mixed through the sauce. Airfry again at 180°C for 6–8 minutes, until bubbling and slightly thickened.
Stir in the peas and spinach. Airfry for a final 3–5 minutes, until the peas are hot and the spinach has wilted into the sauce.
