In a large skillet over medium heat, add the 1 tablespoon extra virgin olive oil . Add the 2 pounds 80/20 ground beef, breaking into pieces and browning until no pink remains, approximately 5 minutes.
Stir in the 1 teaspoon coarse kosher salt, 1 teaspoon ground black pepper, 1 tablespoon garlic powder and 1 tablespoon onion powder.
Drain any excess fat, if there is just a little, don't worry about it. Stir in the uncooked 16 ounces dry elbow macaroni and 32 ounces low sodium beef broth . Spread evenly in the pan, simmering on low. Stir twice to ensure all of the pasta has had a chance to soak up the broth. Simmer for 7-9 minutes, or until pasta is al dente.
Fold in the 1 cup whole milk and grated 3 cups cheddar cheese until incorporated and cheesy. Fold in the 16 ounces petite diced tomatoes.
