• 500 g (1 lb.) sirloin steak, in one piece
• 1 medium red onion, sliced
• 1 small red pepper, seeded and cut into thin strips
• 1 small green pepper, seeded and cut into thin strips
• 1 small yellow pepper, seeded and cut into thin strips
• 4 cloves garlic, crushed
• 125 ml (1⁄2 c.) freshly squeezed lime juice
• 30 ml (2 tbsp.) olive oil
• 30 ml (2 tbsp.) balsamic vinegar
• 5 ml (1 tsp.) ground cumin
• 2 ml (1⁄2 tsp.) salt
• 1 g (1⁄4 tsp.) black pepper
• 1 serrano or jalapeño pepper, seeded and finely chopped
• 8 medium flour tortillas (15 cm/6 in.), warmed following package directions
• 110 ml (4 oz.) cheddar cheese, coarsely grated

1. Combine steak, onion and pepper in a shallow baking dish. Whisk together garlic, lime juice, oil, vinegar, cumin, salt, pepper and chili in a small bowl. Pour over steak mixture; toss to coat. Refrigerate and keep covered for one to two hours.
2. Preheat grill. Cook steak about 10 centimetres (four inches) from heat, for two minutes each side.
3. Add the onion and pepper. Spoon any remaining marinade over steak and vegetables. Grill, turning meat and vegetables occasionally, until the meat is cooked as liked and vegetables are crisp-tender, about a further seven minutes. Leave meat to stand five minutes.
4. Cut meat diagonally across grain into thin slices. Divide meat, onion and pepper evenly between warmed tortillas. Top with cheese.
5. Place under grill just until the cheese melts, about 30 seconds. Fold tortillas over filling and serve.
