• 2 tablespoons olive oil
  
• One 4-pound boneless beef chuck roast
  
• 1 tablespoon onion powder
  
• 1 tablespoon garlic powder
  
• 1 tablespoon dried oregano
  
• 2 teaspoons salt
  
• 1/4 teaspoon black pepper
  
• 5 large onions, chopped
  
• 1 can (28 ounces) diced tomatoes, undrained
  

Sprinkle the onion powder, garlic powder, oregano, salt, and pepper over the roast, then add the onions and tomatoes to the pot.

Reduce the heat to low, cover, and simmer for 2-1/2 to 3 hours, or until the roast is tender.

Slice the roast across the grain and serve with the pan juices.
