Pour the tamari into a large dish and stir in the curry powder, cumin, garlic and honey.
Mix well. Slice the chicken breasts in half horizontally to make 4 fillets in total, then add to the marinade and mix well to coat. Set aside in the fridge for at least 1 hr, or overnight, to allow the flavours to penetrate the chicken.
Meanwhile, mix the peanut butter with the chilli sauce, lime juice, and 1 tbsp water to make a spoonable sauce. When ready to cook the chicken, wipe a large non-stick frying pan with a little oil. Add the chicken and cook, covered with a lid, for 5-6 mins on a medium heat, turning the fillets over for the last min, until cooked but still moist. Set aside, covered, to rest for a few mins.
While the chicken rests, toss the lettuce wedges with the cucumber, shallot, coriander and pomegranate, and pile onto plates. Spoon over a little sauce. Slice the chicken, pile on top of the salad and spoon over the remaining sauce. Eat while the chicken is still warm.
