Pour 1/4 cup water into the pan and bring to a boil while scraping the browned bits of food off the bottom of the pan with a wooden spoon.
2. 2 Layer spaghetti strands on top of meat in a crisscross pattern. Pour marinara sauce over pasta. Pour diced tomatoes over sauce. Pour remaining 3 cups water around sides and on top of tomatoes. Push down lightly with a spatula to make sure water gets through layers and all pasta is covered.
