Preheat oven to 180 C / Gas 4. Coat a large baking dish with cooking spray.
Place the spinach in a medium bowl. Microwave, uncovered, on high for 4 minutes. Mix in ricotta. Beat the egg well, and add it to the spinach and ricotta. Stir well to blend.
Combine white sauce with milk in a medium bowl. Mix well.
Spread about 8 tablespoons of white sauce mixture evenly in the bottom of the dish. Place 3 uncooked lasagne sheets over the sauce. Spread half of the spinach mixture over the lasagne sheets. Sprinkle with half of the carrots and half of the mushrooms. Place 3 more lasagne sheets over the vegetable mixture. Pour 350ml of sauce over the lasagne sheets. Spread the remaining spinach mixture over the sauce, followed by layers of the remaining carrots and mushrooms. Place 3 more lasagne sheets over the vegetables. Pour remaining sauce evenly on top. Sprinkle with the mozzarella cheese. Spray a sheet of aluminium foil with cooking spray. Cover the dish tightly with aluminium foil, coated side down.
Bake for 50 to 60 minutes. Remove from oven, uncover, and spoon some sauce over the exposed top noodles. Turn the oven off, and place the uncovered dish back into the warm oven for 15 more minutes. Serve at once, or let rest until ready to serve.
