I adapted this from an older recipe that used tortillas. We didn't have any, so I broke up some lasagna noodles instead and added more liquid. (You could use a package of store-bought noodles or other pasta.) I also used cream cheese instead of the usual grated Cheddar or Jack.
Salsa-Style Skillet Dinner
1 lb. ground beef
1 cup salsa
1 cup beef broth or water (not necessary with tortillas)
1/2 cup milk
1 can condensed tomato soup or equivalent
4 oz. (half a package) cream cheese
6 to 10 lasagna noodles, broken up (how many depends on the size of your skillet--leave room for the pieces to expand. Adjust liquid as needed).
Brown ground beef and drain fat. Add salsa, broth, milk, and soup and bring to bubbling. Add noodles and cream cheese (don't worry about stirring it in at first--it will soften), cover the pan, and simmer, stirring occasionally, until the noodles are soft. I didn't need to add more liquid, but you might if you have a lot of noodles.
