Thai grilled beef salad

1. Prepare the Beef:

- Rub the beef fillets with the olive oil and season with salt and pepper.
- Grill the beef fillets for about 4-5 minutes on each side for medium-rare, or until they reach your desired level of doneness.

- In a small bowl, combine the fish sauce, lime juice, brown sugar, and chili powder. Stir until the sugar is dissolved.

4. Assemble the Salad:
