Sure! Leftovers will last in the fridge for up to a week, or in the freezer for up to three months. If you're freezing it, I recommend freezing into individual portions using silicone muffin cups, delitainers or Souper Cubes. If frozen, allow to defrost in the fridge overnight before reheating for best results. When you reheat the zucchini bread oats, just note that you'll likely want to add some extra milk or water to help thin them out. You can reheat them on the stovetop or in the microwave in short bursts.
