1. Slice the chicken into 1cm strips. Pan-fry in the oil until just cooked, about 5 minutes.
2. Combine the sauces, brown sugar and paprika and stir into the chicken. Heat for a few seconds.
3. Meanwhile, line the bases of the bagels with the lettuce leaves. Trim the spring onions. Thinly slice the green ends so they will curl then place in icy water.
4. Top the lettuce with the sticky chicken. Sprinkle with sesame seeds, cover with the bagel top and insert a spring onion curl in the bagel hole.
