Place a steamer basket in a large saucepan, and add 1½ cups water. Add cauliflower florets to the basket. Cover and bring to a boil. Reduce to simmer then cook for 8-10 minutes until fork tender.
Combine steamed cauliflower in a blender with milk and ricotta cheese, and blend until smooth.
Stir in mozzarella, parmesan, and an egg. Set aside.
Chop up mushrooms, carrots, and onion finely, or shred them using a food processor.
Heat olive oil in a saucepan over medium high heat.
Add the chopped vegetables, ground beef, salt, and pepper, and cook stirring until the meat is browned - about 4-5 minutes.
Drain the grease, then return to heat. Pour in marinara sauce then stir. Heat until it starts simmering, then turn off heat.
Stir in pasta. Preheat the oven to 350 degrees F.
Add half of the pasta sauce mixture to a 9x13 baking dish.
Spoon the cauliflower ricotta mixture on top, using the back of a spoon to spread into an even layer.
Add the rest of the pasta mixture on top.
Cover with foil, and bake for 40 minutes.
Uncover, and top with mozzarella and parmesan. Bake uncovered, for 10-15 minutes until bubbly and cheese is melted.
Rest for 5-10 minutes before serving.
