Preheat the air fryer: Set it to 375°F (190°C) for a few minutes while you assemble the sandwich.
Prep the flatbread: Lay the flatbread on a board. Lightly spray or brush one side with olive oil. This will be the outside.
Add your spread: On the non-oiled side, spread hummus, pesto, or your sauce of choice in a thin, even layer.
Layer the cheese and protein: Add cheese first to help “glue” the sandwich together, then layer on your protein.
Add veggies and season: Top with leafy greens, tomato, and onion.
Sprinkle with salt, pepper, and a pinch of garlic powder. If using avocado, add it now for creaminess.
Fold or roll: For round flatbread, fold in half like a quesadilla. For lavash, roll it up snugly like a wrap.
Press gently to help it hold.
Air fry: Place the sandwich oiled-side out into the basket. Air fry at 375°F (190°C) for 3–4 minutes, flip, then cook 2–3 minutes more until the bread is crisp and the cheese is melted.
Rest and slice: Let it sit for 1 minute so the filling sets. Slice in halves or thirds for easy eating.
Pack for work: Wrap in foil for warmth or store in a container with a paper towel to keep it crisp.
