Crisp October air means the beginning of soup season! But if you’re like me and short on time, slow cooker soup is definitely the way to go. Not only will you have a delicious meal waiting for you when you get home for work or running around, your house will smell ah-mazing, too!

Last week, the Bug had an ‘ear infechin’ and wanted the ultimate comfort food: grilled cheese and tomato soup. I’m a firm believer that the quality of your cooking depends on the quality of your ingredients — so when I found San Marzano whole canned tomatoes on sale at Whole Foods, whipping up some tomato soup was a no-brainer. The tomatoes are a bit pricier than what you may be used to — but try them. I swear you will never go back!

Enjoy this sure-to-please-em-all recipe!
