Heat the bone broth until boiling—either on the stovetop or in the microwave. If using broth powder, boil the kettle.
Place the noodles, frozen vegetables, and any optional add-ins into a heatproof jar or bowl. (If using broth powder, sprinkle it over the noodles.)
Pour the hot broth over the ingredients, screw on the lid or pop a plate on topic and let sit for 3–4 minutes until the noodles and veggies are tender (if using a thermos they will keep cooking for a while!)
Give it a quick stir, and enjoy your nourishing, flavour-packed noodles!
