Easy, Tasty, Healthy

This easy-to-assemble, hearty slow cooker soup recipe is healthy, tasty, and a great way to use up leftover cooked ham from a holiday meal.

I made up this recipe when trying to come up with creative ways to use leftover ham after a big holiday meal. I do like traditional lentil soup, but find that many people find the brownish color a little off-putting—especially kids. The addition of diced tomatoes results in a more appealing reddish-colored soup, and the vitamin C in the tomatoes improves the absorption of the iron in the lentils.
