Prepare the pasta by following the directions on the package.

In a large pan, heat the olive oil. Add the garlic and stir for 30 seconds - just enough time to release its aroma. Add the spinach and stir until uniformly wilted. Remove from the heat and cool.

Using a 9" by 13" pan to prepare the lasagna, coat the bottom of the pan with a small amount of marinara sauce. Layer the pasta, marinara sauce, spinach, feta, olives, mozzarella cheese, parmesan cheese and another layer of pasta. You will repeat this action three times. To top your lasagna, cover with a layer of pasta, marinara sauce and then mozzarella and parmesan cheese.

Bake in a 350 oven for 45 minutes or until hot. Cover if top becomes too brown. Let rest at least ten minutes before cutting.
