I always feel so clever when I’m able to turn leftovers into something new and tasty. This vegetable beef lentil soup is a great example.
I had several odds and ends in the fridge, including about 3 ounces of beef, a few potatoes and onions and a little gravy from Sunday’s Slow Cooker Pot Roast, about a cup of lentils that I didn’t need for Wednesday’s lentil salad, a half a cup of mashed potatoes, and a half a tomato left from lunch.
Instead of letting them go to waste I scavenged around to see what else I could add to them to turn into a little pot of soup and came up with a cup of frozen corn, a cup of frozen mixed vegetables, and some boxed beef broth.

So I dumped everything into a large saucepan, stirred it altogether, added about a half a teaspoon of thyme and let it simmer for just under an hour, giving it a stir every once in a while.
Then I tasted it and was happily surprised. It was really pretty good!
Recipe Notes and Variations
Rod and I had some of it for supper last night. There was still quite a bit left, so I called Mom and invited her to join me for lunch. She brought along salad and a loaf of crusty bread, turning my simple soup into a lovely meal.
This is one of those recipes that would be tricky to replicate, since it’s such a hodgepodge. But it’s a perfect example of how easy it is to turn leftovers into soup.

Just take your leftovers, and other things you think would taste good with them and place them in a large saucepan, add some broth, sprinkle in your favorite spices and let it simmer until everything is tender and the flavors have blended. That’s all there is to it!
