These broccoli and mushroom quesadillas are quick to make, crispy on the outside, and filled with good stuff. You fry mushrooms and tenderstem broccoli until golden, season it well, then layer it between tortillas with grated mozzarella (or dairy-free cheese if that’s your thing).A bit of chilli and garlic adds warmth, and hazelnuts give a nice little crunch. These make a brilliant lunch or simple dinner.
