Melt the butter in a pot and brown the meat while stirring over high heat.
Add all the vegetables, chopped tomatoes, tomato paste, oregano, thyme, vegetable stock, and cream.
Let it simmer without a lid for 10-15 minutes.
Season with salt and pepper.
Grease an ovenproof dish and alternate layers of sauce and lasagna sheets. Start and finish with a layer of sauce.
Bake the lasagna for 20 minutes at 175 degrees Celsius (347 degrees Fahrenheit) (fan).
Take the lasagna out, spread the cheese on top, and bake for another 5-10 minutes until the lasagna sheets are soft.
Take the lasagna out and garnish with, for example, parsley.
Serve with good bread and a salad.
Fresh spinach goes very well with it.
Enjoy!
