Notes

Nutritional information does not include any additional toppings. 
Storing: Leftover mushroom fajitas can be stored in an airtight container in the fridge for up to four days. Because the vegetables contain a high amount of water, freezing is not recommended as they will become too mushy when thawed.
Reheating: To reheat leftovers, simply add them to a skillet over medium heat until warmed through. You can also reheat them in the microwave, but be careful not to overcook or they will become mushy.
