Yes, Aubergine Spinach Dhal freezes well. Allow it to cool completely before transferring it to freezer-safe containers or zip-top bags. It can be stored in the freezer for up to 3 months. To reheat, thaw it overnight in the refrigerator and then reheat it on the stovetop or in the microwave. You may need to add a little liquid to loosen the dhal when reheating.
