In a small bowl, mix together the grated cheeses, butter and chilis. You want to make a bit of a paste with all this before you spread it on the bread, because if you don't, you will have airborne shreds of cheese flying about the air fryer.
Spread this paste on to the 2 slices of sourdough bread.
Place the slices of bread on in the air fryer basket and cook at 330F for 5 minutes, until the cheese has melted.
Tips And Tricks For Making Chili Cheese Toast
Roasted chilies get pretty spicy, so be a little careful how many you put on each slice.
If you want it hotter though, add some ground black pepper to amp up the spice.
You can make the cheese, butter and pepper mixture ahead of time and keep it in the fridge for whenever you get the craving for more Chili Cheese Toast.
