Its as simple as pie to make. Maybe even simpler... if you use ready to bake noodles. You will need: lasagna pasta, baby spinach leaves, ricotta cheese, mozzarella cheese, soup stock, tomato sauce and or diced tomatoes.
To begin, heat your oven to 425. While it heats up, prepare the lasagna. Either use ready to bake noodles or ordinary precook. Lasagna is all about the layers. Its best to start the layering by putting down a layer of lasagna noodles 'dry or precooked' into a glass baking dish drizzled with olive oil. Cover each noodle with a spoonful of soup stock.
Next, add the meat (or not) of your choice; cooked and crumbled in. Pour over this, tomato sauce (or diced tomatoes), then a layer of grated mozzarella cheese topped with a sprinkle of dried herbs. Repeat this reserving the middle layer for the baby spinach leaves and ricotta cheese.
Put another layer of noodles, stock and sauce, top with mozzarella cheese (a few slices of whole tomato looks nice) and more dried herbs: rosemary, mint/basil and oregano.
Bake in the oven uncovered for at least 60 min keeping an eye on things. After 30 min. or so, add Parmesan cheese. Let it cook until bubbling over. Let cool before serving; and, have extra sauce on the side to spoon on or around the lasagna.

*if making vegetarian, omit the meat and just use spinach leaves in all layers.
