I found this in my Campbell's Classic Recipes cook book. I made it according to directions and it was good, but we all agreed that next time I should add beans and/or corn.
1 pound ground beef
1 can (10 3/4 oz) Condensed Tomato Soup
1 cup thick salsa or picante sauce
1/2 cup milk
6 flour or corn tortillas (small size), cut into 1 inch piecies
1 cup shredded cheddar cheese
(Again, I would add a can of kidney or black beans, or some frozen corn, as well.)
In a medium skillet, cook ground beef until brown. Add soup, salsa, milk, tortillas, and HALF of the cheese. Spoon into 2-qt shallow baking dish. Cover. Bake at 400 degrees for 30 minutes or until hot. Sprinkle with remaining cheese.
