Black pepper Prawn Gratin

Prep everything first: chop the aromatics, measure the black pepper elements, and pat the prawn dry so it colours well.

Warm the olive oil in a large pan over a medium heat and soften the onion and garlic until sweet and translucent, about 5 minutes.

Turn up the heat and add the prawn. Grill over a medium-high heat, turning once, until nicely charred and cooked through.

Stir in the yellow mustard and the rest of the black pepper flavours, letting them cook out for a minute until fragrant.

Add the green beans along with a splash of stock or water, then cook briskly until everything is tender and the sauce clings.
