Freeze the beef fillet for an hour before you prepare it so it's
easier to cut and refrigerate the diced meat as you go so it
remains nice and chilled.

Freeze beef fillet for at least an hour to chill well.
For spicy smoked salsa, char chillies over a gas flame on a stovetop or medium-hot barbecue and turn occasionally until blackened and tender (8-12 minutes). Place in a bowl, cover tightly with plastic wrap and set aside to steam (10 minutes). Peel chillies, discard seeds, finely chop and combine in a bowl with remaining ingredients, season well with salt and refrigerate until required.
Preheat oven to 175C. Toast baguette slices in oven until golden (10 minutes). Set aside to cool.
Finely dice beef and combine with salsa in a bowl and mix well. Add extra-virgin olive oil and lemon juice to taste and mix to combine, then transfer to a chilled plate, top with a dollop of yoghurt, scatter with herbs, season well, and serve with croûtes to the side.
