Tip the couscous into a medium bowl, pour over 75ml/21⁄2fl oz boiling water and leave it for a few minutes to swell and absorb all the water. Add the mince, onion, dried herbs, chives and chilli powder then grind in plenty of salt and pepper. Mix thoroughly then shape into 6 oval burgers – slightly larger than the bread slices.Cover with foil and chill until ready to cook. (Can be made up to 24 hours ahead.)
Preheat the grill or barbecue
then cook the burgers for 5-6
minutes on each side, or more
if you like them well cooked.
Grill or lightly toast the slices of bread and spread with mustard. Top with the peppers, rocket and a burger and serve.
