Prepare a BBQ or cast-iron griddle pan for cooking over a high heat.

Rub the nectarines with a little oil and cook, cut-side down, for about 5 mins, turning occasionally, until charred and softened.

Once cool enough to handle, dice the grilled nectarines and combine in a bowl with the tarragon, basil, chilli flakes, lemon and lime juice and a little salt.

Rub the halloumi with a little oil and cook quickly on the BBQ or griddle pan for a minute or so on each side, or until charred. Serve immediately with the nectarine mixture.
