"This was perfect..making it for my husband with leftover roast beef because I am going on a trip, and he'll need something to tide him over! The meat turned out so tender..the lentils add body to this soup."

"Had carrots, potatoes and onions left over with roast. Cubed all and placed in 8 qt saucepan. Added leftover gravy, 1 can beef broth, 1 qt jar home canned tomatoes with juice, 1 can corn with liquid, 1 can cut green beans with liquid, salt, pepper and 4 cups water. Came out great and used all my leftovers."

"Wonderful flavoring but just note that it takes longer to cook. It might be a typo -- 1 hour 40 minutes. Also, since I didn't have roast beef left overs, I got an order of thick the roast beef from the deli and it worked just fine."
