In a small bowl, whisk together the sauce ingredients and set it aside.
1 (15-ounce) can condensed tomato soup, 1 cup beef broth, 1 teaspoon Worcestershire sauce, 1 Tablespoon brown sugar
Place the ground beef, rice, egg, onions, salt, pepper, garlic powder, onion powder, Worcestershire sauce and 2 tablespoons of the parsley in a medium-sized bowl and mix until just combined.
1 pound lean ground beef, ½ cup long grain rice, 1 large egg, ½ cup finely diced onion, 1 teaspoon salt, ¼ teaspoon pepper, ¾ teaspoon garlic powder, ½ teaspoon onion powder, 1 teaspoon Worcestershire sauce, ¼ cup chopped fresh parsley
Heat the oil in a skillet over medium-high heat
2 Tablespoons canola oil
Form the meatball mixture into even-sized balls (about 2 tablespoons each or 1½ inches in diameter).
Working in batches, add the meatballs to the pan and turn them every 1-1½ minutes to brown all sides.
When the meatballs are all browned, pour the sauce over them. Cover and simmer on low, stirring occasionally, for 35–40 minutes until the meatballs are cooked through and the rice is tender.
Top the meatballs with the remaining parsley and serve hot.
