Preheat oven to 450 degrees Fahrenheit. Coat crinkle-cut sweet potatoes with olive oil, salt and pepper.
Spread on a baking sheet and bake for 15-20 minutes (turning halfway) or until soft to touch.
Remove the fries from the oven, place in a skillet or gather onto the same baking sheet. Sprinkle cheddar cheese on top followed by diced corned beef and green onions.
Place the baking sheet/skillet back in the oven and broil for 3-5 minutes until cheese has melted and corned beef begins to crisp.
Notes
Corned beef - You can use about 2 deli slices of corned beef for this recipe if you don't have leftover corned beef.
Cheese - If you don't have shredded cheddar cheese you could always use swiss cheese.
