If you're a fan of mushrooms, you'll love this Thermomix recipe for air fryer grilled cheese. Start by sautéing sliced mushrooms in the Thermomix until they're golden brown and tender. Then, assemble your sandwich with Swiss cheese and the sautéed mushrooms. Cook it in the air fryer until the cheese is melted and the bread is crispy. The earthy flavor of the mushrooms pairs perfectly with the creamy Swiss cheese.
