I own a ton of cookbooks, but if I had to choose the one I use the most often in my kitchen, it's Fresh from the Vegetarian Slow CookerChard, Lentil & Potato Slow Cooker Soup Recipe (2) by Robin Robertson. This is my book that has notes scrawled all over the pages and food spatters on the most frequently used recipes. If you're a vegetarian and you own a slow cooker, you should really buy this book!

This recipe is adapted from a kale and lentil soup that's in Fresh from the Vegetarian Slow Cooker.Chard, Lentil & Potato Slow Cooker Soup Recipe (3) It's not super fancy, it's not a show-stopper, but it's a delicious, hearty soup for a chilly fall evening. I replaced the kale with chard—and used a lot more than the original recipe calls for. We love Swiss chard, and if I was buying a whole bunch anyway, why not use it? I even threw in the stems, so nothing goes to waste! I also added some Yukon potatoes to make this soup even more filling, but sweet potatoes or butternut squash would probably be just as tasty.

Why do you love this cookbook?

The thing I love about Fresh from the Vegetarian Slow Cooker is that the recipes are mostly unfussy. You might have to sauté some ingredients before putting them in the crockpot. But other than that, things are pretty uncomplicated—which is what I like in a cookbook. I want realistic, everyday meals. I want a cookbook I can use, not one with lots of pretty pictures of recipes that are a such pain to assemble that I'll probably never make.

When I was working full-time and going to library school full-time (yeah, that happened), I worked my way through a good half of the recipes in this cookbook. They were so easy to put together! I could let them cook in the crockpot all day and dinner would be ready when we got home. Without fail, they were all winners. The best part was that there were always leftovers, so we could have them for dinner the next day or freeze them. The only thing easier than a slow cooker meal is a leftover meal! Or stopping at Chipotle on the way home from work. (Yeah, that happened too.)

Can I freeze this soup?

You can easily freeze this soup. Simply let it cool down a bit, pour it into freezer-friendly containers or ziplock bags, and pop it in the freezer until you're ready to eat it again! I recommend separating the soup into serving-size portions so you don't have to thaw all of your frozen soup when you only want to eat one cup.
