Thread the olives onto metal or bamboo skewers. Heat a griddle pan or light the barbecue, then when the flames have died down and the coals are white, toss the spring onions with the oil and grill for 8-10 mins to cook until tender. Grill the olives for a few mins, turning regularly, until they look a little charred. Remove the spring onions from the grill and cut into bite-sized pieces. Remove the olive skewers from the grill.

Heat the grains and rice pouches, if using, in the microwave for 2 mins until warm. Toss with the vinegar, some seasoning and the sundried tomatoes with a little drizzle of the oil from the jar. Leave for a few mins for the dressing to be absorbed.

Toss the olives, spring onions, toasted almonds and celery into the rice. To serve, stir through the manchego, if using, and season to taste.
