You can easily swap out any of these suggested veggies for your favorites. I have tried this recipe with cauliflower, asparagus, and zucchini as well and they are all delicious and work perfectly.
Pro Tip for reheating: I highly recommend investing in an inexpensive plastic splatter guard (sold at almost any grocery store like Walmart, Target, etc) and using whenever you are reheating, especially for a dish like this one - not only will it keep your microwave from getting messy, it will also act as a bit of a steamer and keep a lot of the natural moisture in the food so it doesn't get dried out.
