Make salsa according to recipe - set aside in the fridge until ready.
Season steak generously with salt and rub with oil - set aside.
Drizzle tomatoes with approx 1 tbsp olive oil and a generous amount of salt. Roast in the oven at 160c for 15 minutes.
Meanwhile, heat a cast iron pan or bbq on high until piping hot. Place 1 tbsp oil in cast iron and add steaks cooking for 1.5/2 minutes per side until internal temperature is 55-58c. Remove steaks from pan and leave to rest for a further 5 minutes
While steaks are resting slice bread to desired thickness, drizzle with oil and grill until golden
To serve - slice steak thinly and place all the ingredients on large wooden board and let everyone dig in. Bread, brie, steak, tomatoes & salsa = job done!
