First of all, begin by roasting the red pepper in the air fryer for 8 minutes at 215°C. After roasting, transfer it to a bowl and cover it with a plate. This creates a steaming environment that helps the pepper cool and makes it easier to peel. The steaming process ensures that the skin can be removed effortlessly.
Then, toasting the bread in the toaster or air fryer. Set aside.
Slice the tomato, then combine it with thinly sliced red pepper. Drizzle with olive oil, vinegar, and add salt, oregano, and garlic powder to taste.
Spread this mixture over the toasted bread.
Place the sardine on top.
