Heat oven to 350°F. Cook and drain pasta shells as directed on box.
Meanwhile, in 12-inch skillet, cook beef over medium-high heat 5 minutes, stirring occasionally, until thoroughly cooked. Add cooking sauce and salt; mix well to combine. Add 1/2 cup of the tomatoes and 1/2 cup of the cheese; stir well.
Using about 1 heaping tablespoon beef mixture in each, fill cooked pasta shells; place in ungreased 13x9-inch (3-quart) glass baking dish. Sprinkle remaining 3/4 cup tomatoes and chopped cilantro over filled shells. Top evenly with remaining 2 cups cheese.
Bake 15 minutes or until cheese is melted.
