Sweet Potato Shepherd’s Pie

1 lb. ground meat, any type
1/2 med. onion, diced
1 tbsp. olive oil
2 tsp. garlic salt
1 1/2 tsp. salt
1 tbls. oregano
1 (15.25 oz.) can of corn, drained
2 lbs frozen green beans
1 (15 oz.) can tomato sauce
2 c. sweet potatoes, cubed (approx 3 med. potatoes)
1/2 c. shredded cheddar cheese

Preheat oven to 350. In a medium pot, boil sweet potato cubes until soft; approx. 10-15 minutes (depending on the size of your cubes). While sweet potatoes are boiling, heat olive oil on medium-high in a large pan and saute onions until translucent; 3-5 minutes. Add ground meat; brown and season with garlic salt, salt & oregano. Add corn, green beans and tomato sauce. Heat throughout. Once potatoes have softened, drain all water and mash with a potato masher, hand held immersion blender, or hand mixer. Spoon meat mixture into the bottom of a casserole dish and cover with prepared mashed potatoes. Sprinkle the pie with shredded cheese and bake for 15 minutes until heated through and cheese is melted.
