I forgot to buy scallions for okonomiyaki. Substitution or omission suggestions?

Question

I could substitute a little sautéed diced onion, or drag my toddler to a grocery store to buy the scallions.  Thanks ...

I would use thinly sliced, not diced, onions. But if you've already diced the onions, go ahead and use it.

Chives would be best, otherwise thinly sliced shallots?
