Cook your lasagna noodles until al dente if they aren't oven-ready. Drain and lay them flat on a clean surface to cool. Trust me, this small step makes rolling them easier later.
Sauté minced garlic in butter until aromatic. Toss in the mushrooms and kale. Stir occasionally until the veggies are tender, and the mushrooms release their moisture. Cool the mixture slightly, then mix it with ricotta, mozzarella, Parmesan, salt, and pepper in a bowl.
Steam or boil cauliflower florets until soft. Blend them with warm milk, butter, and crumbled Gorgonzola. Voilà! You’ve got a smooth, creamy sauce. Add salt and pepper to taste. Feeling fancy? Add a pinch of nutmeg for extra warmth.
Spread a spoonful of the mushroom-kale mix along the length of each lasagna noodle. Roll them up tightly and place them seam-side down in a greased baking dish.
Pour a layer of cauliflower sauce at the base of the dish. Nestle your roll-ups in and generously cover them with the rest of the sauce. Sprinkle extra mozzarella and Parmesan on top, then cover with foil. Bake at 375°F for 20-25 minutes until bubbly!
Remove foil for a golden-cheese finish, garnish with parsley or extra Gorgonzola, and dig in hot. Your masterpiece is ready to shine!
