Seaweed Soup (Miyuk Guk)

Soak miyuk in a large bowl of cold water for about 30 minutes. Rinse two or three times and drain. Cut into bite-size pieces, if necessary.

Toss chicken in a large bowl with garlic, tamari and 2 teaspoons oil. Let marinate at room temperature for 15 minutes.

Heat the remaining 1 teaspoon oil in a large heavy pot over medium-high heat. Add the chicken and cook, stirring often, until no longer pink on the outside, about 1 minute. Add the drained miyuk and cook, stirring often, for 3 minutes more.

Add broth; bring to a boil over high heat, skimming off any foam that rises to the top. Reduce heat to maintain a simmer and cook for 30 minutes. Serve sprinkled with sesame seeds, if desired.
