Mexican Bean Tortilla Lasagna

In the meantime, ready a deep oven dish that is the right size for your lasagna. If you don't have one, get creative with tinfoil. Use 2 layers to create your dish and be sure it has sides about 7cm high. Lightly grease it to prevent the lasagna from sticking. Place your first tortilla on the base of it. CHEFS TIP: depending on the size and shape of your baking dish, you may need to manoeuvre the tortilla or nip and tuck to fully cover the base. We gave you an extra incase!
