Ingredients
- 500 g sirloin steak
- 1 red pepper, thinly sliced
- 1 yellow pepper, thinly sliced
- 1 red onion, thinly sliced
- 2 tablespoons cajun spice mix
- 60 ml olive oil
- Juice of 1 lime
- 1 avocado, sliced
- 150 g sour cream or Greek yoghurt
- 1 small bunch fresh coriander, chopped
- 8 to 10 small flour tortillas
Instructions
- In a shallow dish, mix Cajun spice mix, olive oil, and lime juice. Add the sirloin steak and coat well. Marinate for at least 15 minutes.
- While the steak marinates, thinly slice the peppers and onion.
- Heat a large skillet over high heat. Sear the steak for 4–5 minutes per side, then remove and let it rest.
- In the same skillet, cook the red onion until soft and golden. Add the peppers and cook until tender but still vibrant.
- Pour in any remaining marinade and simmer until slightly thickened.
- Slice the rested steak against the grain and return it to the pan. Toss everything together to combine.
- Warm tortillas in a dry pan or microwave.
- Fill tortillas with steak and veggies. Top with sour cream or Greek yoghurt, avocado slices, and fresh coriander. Serve warm.
Notes
- Resting the steak before slicing helps retain its juices.
- Prep the marinade and vegetables ahead of time for faster weeknight cooking.
- Swap in flank or skirt steak for different texture and flavour.
- Add lime wedges, fresh chilli, or cheese for extra toppings.
