If you make up the lasagne from scratch (ie raw ingredients) as Chickadee & Puddicat mention, it shouldn't cost too much. I start off with the tomato sauce - canned tomatoes, onions, garlic, oil, herbs and a chilli (or 3 lol), seasoning (salt, pepper and a bit of sugar) and let them all cook up and make friends in a large pan. In a separate pan I make up a bechamel sauce, then add loads of different cheeses (say, applewood, caerphilly, mature cheddar - no mozzarella, that's for pizzas, it's too gooey for lasagne). I saut� some vegetables (mushrooms, peppers etc) and add some fresh kale or spinach, wilt them down and then arrange layers of wholewheat lasagne, tomato sauce, vegetables (repeat as necessary) with a final topping of bechamel & cheese sauce and bake in a medium oven (200 deg C) for about 30 minutes until bubbling and golden brown... then devour .... lol
