In a medium pan over medium-high heat, sauté the onions and garlic until they caramelize.

In a separate pan, brown the meat making sure not to cook through.

Add the onions, garlic, beef, beans, tomatoes, potatoes, celery mushrooms, cumin, sea salt, black pepper, and beef broth to your slow cooker.

Cook 1-2 hours on high heat or for 4-6 hours on low.

In the last 15 minutes on high, or last 30 minutes on low, add the mixed vegetables, and spinach.

Once cooked, top with cilantro and a squeeze of lime.
