Delicious comfort food dinner! I added a can of diced tomatoes as recommended by another reviewer. Used sharp cheddar as it's what I had. I probably used 3 cups of pasta and 3/4 cup pasta water. I mixed all the cheese into the dish. I also started the onions first and then added the ground beef. Overall excellent meal that was enjoyed by everyone and was great the next day with a 20 second microwaving.
