Add olive oil to a frying pan, and fry garlic and leeks until golden. Add spinach, zucchini, lemon juice and dill and let simmer for a couple of minutes.
Add some of the spinach to a small ovenproof dish. Cover with gluten-free lasagna sheets, top with cheese and then repeat until you have used up all the lasagna sheets and the spinach.
