Over medium heat, heat your olive oil and minced garlic until it becomes fragrant.
Add the corn and shredded turkey to the skillet and saute for a moment.
Salt and pepper to taste then add the gravy. Keep over medium heat until everything is well-mixed.
Spread half of the mashed potatoes into the bottom of a baking dish.
Add the turkey mixture, then the rest of the mashed potatoes on top.
Sprinkle the top with cheese.
Bake for 30 - 35 minutes, or until golden brown!
Notes
*Feel free to add any other leftover veggies as well! **I use a mixture of cheddar and Parmesan, so go with whatever you prefer! You can always add a fresh layer of cheese after taking your casserole out of the oven, too.
