I know cabbage doesn't exactly scream "exciting dinner," but hear me out. This soup is the kind of thing you throw together when you need something warm, filling, and actually good for you - perfect for Winter soup season. The cabbage gets tender and sweet as it simmers, the spices give it way more personality than your typical cabbage soup, and that hit of spinach at the end adds a pop of color and extra nutrients.
I used to be weirdly intimidated by cooking with cabbage. It just sat there in my fridge looking massive and vaguely threatening. But once I realized you can literally just chop it up and throw it in soup, it became one of my favorite budget-friendly vegetables. This recipe is basically my answer to those viral 90s "cabbage soup diet" recipes, except we aren't restrictive eating anymore. It's all about balanced nutrition! I added spinach for extra greens, used the "good" seasonings, and made something you'd want to eat because it tastes delicious and comforting.

How to Store and Reheat
- Storage - Let the soup cool completely, then transfer to airtight containers. It will keep in the fridge for up to 5 days.
- Freezing - This soup freezes beautifully for up to 3 months. I like to freeze it in individual portions for easy grab-and-go lunches or weeknight dinner.
- Reheating - Reheat on the stovetop over medium heat until warmed through, adding a splash of broth if it's thickened up. You can also microwave individual portions for 2-3 minutes, stirring halfway through.
