Slow cooker Sweet Potato, Carrot and Lentil Soup

So yesterday I saw my housemates slow cooker sitting on the counter and inspiration struck. I googled a few different recipes and ended up winging it and throwing a bunch of stuff in a pot. Specifically, a sweet potato, some carrots, red lentils and onion. Plus some curry powder and a dash of cumin and cinnamon. And vegetable broth! Then I put it on low and let it sit all day.

And tada! A hearty and healthy and delicious and flavorful thick warm winter soup! 

Notes to self: presoak the lentils! For some reason, even after hours and hours, they were still crunchy...mysterious
