1-1/2 pounds beef top sirloin steak, thinly sliced
3 tablespoons canola oil
1 small onion, chopped
2 large green bell peppers, cut into strips
1 garlic clove, minced
1 can (28 ounces) diced tomatoes, undrained
2 to 3 tablespoons beef broth
1-1/2 teaspoons Worcestershire sauce
Instructions
In a shallow dish, combine flour, salt and pepper. Add beef slices, a few pieces at a time. Toss gently to coat.
In a Dutch oven, heat oil over medium-high heat. Brown beef in batches. Add onion; cook and stir until tender, 3-4 minutes. Add garlic; cook 1 minute longer. Add tomatoes; bring to a boil. Reduce heat. Simmer, covered, stirring occasionally, until meat is tender, 10-15 minutes.
Stir in green peppers, broth and Worcestershire sauce; simmer, covered, until peppers are tender, 10-15 minutes.
