Preheat oven to 400 degrees. Wash potatoes with water. Dry with paper towels. Drizzle potatoes with vegetable oil and then sprinkle evenly with kosher salt. Poke a couple holes at the tops of potatoes with a fork and place them on a baking sheet. Bake for 1 hour or until fork tender.
When potatoes have about 20 minutes left to bake, start on sauce.
In a large skillet, brown ground beef over medium-high heat. Drain any grease. Pour in tomato sauce and soup and then sprinkle in garlic powder, onion flakes and chili powder. Stir well. Pour in milk, green beans and corn. Continue to stir and cook until mixture boils. Reduce heat to low and let simmer until potatoes are ready.
Once potatoes are finished baking, carefully remove from oven and let rest a couple minutes. Cut a slit on top of each potato and then squeeze sides to open. Top each with desired amount of meat sauce. You can also add shredded cheese, sour cream and chives, but if your watching calories and fat then dont! :) Enjoy!
