Need help deciding a side dish for my husband's birthday dinner!

My name isNatasha, and I LOVE cooking, especially all kinds of cuisines. I’m a Native Yupik Alaskan, born in Alaska, but was adopted and raised in Upstate NY. I love exploring new cuisines and cooking techniques.
My husband’s 33rd birthday is tomorrow and he asked me to make a special birthday dinner for him. He requested miso soup, bok choy muchim, seaweed salad, steamed rice, and a surprise seafood side dish. Can you help me by recommending a special seafood side dish to make for his birthday? I love cooking, especially challenging recipes!
