Chargrilled chilli beef with avocado

1. Marinate the Beef:
- In a medium bowl, combine the minced garlic, red wine, and chili powder.
- Add the beef fillets to the bowl and ensure they are well-coated with the marinade.
- Cover the bowl and refrigerate for at least 30 minutes to let the flavors infuse.

2. Prepare the Salad:
- While the beef is marinating, prepare the avocado, cucumber, and onion.
- In a large salad bowl, combine the diced avocados, sliced cucumber, and onion.
- Add the roughly chopped basil leaves to the salad.

3. Dress the Salad:
- Drizzle the olive oil and vinegar over the salad.
- Gently toss the salad to ensure all ingredients are well mixed and coated with the dressing.
- Set the salad aside.

4. Preheat and Grill:
- Preheat your grill or grill pan over medium-high heat.
- Once the grill is hot, remove the beef fillets from the marinade (discard any leftover marinade).

5. Cook the Beef:
- Grill the beef fillets for about 3-4 minutes on each side for medium-rare, or until your desired level of doneness is reached.
- Remove the beef from the grill and let it rest for a few minutes.

6. Serve:
- Plate the grilled beef fillets and serve with the prepared avocado and cucumber salad on the side.
- Optionally, garnish with additional basil leaves for a fresh touch.
