Halve the green peppers, remove the stem and seeds, and slice into thin strips. Cut the chikuwa into thin strips of a similar size.
Put the green peppers and chikuwa in a heatproof bowl, cover loosely with plastic wrap, and microwave at 600W for about 1 minute 30 seconds until the peppers are softened.
Drain off any water that has collected in the bowl.
Add the shio kombu, soy sauce, and sesame oil and toss until evenly combined.
Sprinkle with toasted sesame seeds. Serve warm, or chill for a bit to let the flavors meld.
