In a medium-sized pot, bring the broth to a boil on high heat.
Add in the noodles and cook for 5 minutes (or adjust the time to the noodle you are using - just take 2 minutes off the recommended cooking time.)
Add in the beans. Boil for another 2 minutes or until the noodles are tender.
Remove the pot from the heat, stir in the spinach, and cover the pot until the spinach is wilted. Add in any seasoning as you see fit.
