In a mixing bowl, whisk the eggs, then add the tomatoes, roast peppers, spinach and a pinch of salt and pepper.
Pour the egg mixture into a greased baking dish and crumble half the feta on top.
Add 250ml water to the inner pot, then place the dish on the trivet and lower inside.
Secure the pressure cooking lid, select pressure cook and set the time for 10minutes.
When the cooking program has finished, allow the pressure to release naturally for 7minutes and then quick release the remaining pressure.
Swap for the air fryer lid and select Grill. Set the time for 7minutes and grill until golden brown.
Once cooked, serve topped with the remaining feta and side salad of choice.
