Season with salt and pepper, to taste, if desired. Mix well to thoroughly combine. (You can make your own mashed potatoes or use pre-made mashed potatoes, such as Bob Evans brand.)
3. Using a slotted spoon, add the vegetable mixture to the mashed potato mixture. Try to avoid adding any excess moisture that may be in the pan. Stir to combine.
4. Spray a 13x9-inch casserole dish with nonstick cooking spray. Pour the mixture into the casserole dish.
5. Top the mixture with the remaining shredded cheddar cheese.
6. Bake in a preheated 350-degree F oven until cooked through and golden brown, about 45 minutes (ovens vary).
7. Allow to cool a few minutes before serving. Store leftovers in an airtight container in the refrigerator and reheat in the microwave or oven.
