1. Step 1: Heat 2 tbsp olive oil in a large deep skillet over medium-high heat. Add 1 lb Italian sausage (casings removed) and cook for 5-6 minutes, breaking it apart until browned.
2. Step 2: Add 1 diced medium onion and 3 minced garlic cloves to the skillet, sautéing for 3-4 minutes until softened and fragrant.
3. Step 3: Stir in 4 cups chopped fresh spinach and cook until wilted, about 2 minutes.
4. Step 4: Pour in 3 cups marinara sauce and 2 cups water, then add 8 oz broken lasagna noodles. Season with 1 tsp salt, 1/2 tsp black pepper, and 1 tsp dried Italian seasoning. Stir gently to combine.
5. Step 5: Bring to a simmer, cover with a lid, reduce heat to low, and cook for 15-18 minutes until noodles are tender, stirring occasionally to prevent sticking.
6. Step 6: Remove the lid, sprinkle 2 cups shredded mozzarella and 1/4 cup grated Parmesan evenly over the top. Cover again and cook for 3-5 minutes until cheese melts and bubbles.
7. Step 7: Let rest for 5 minutes before serving to allow the layers to set.
