Dairy-Free: to make this dairy-free use a plant-based butter.
Couscous: I used Moraccan-style couscous for this recipe - you can use a pearl or other type of couscous BUT you may need to change the cook time, etc. Simply look at the package instructions and cook accordingly.
Storage: store leftovers in an airtight container in the refrigerator for up to 5 days.
