okonomiyaki!
we use the batter instructions from this recipe:https://www.bbcgoodfood.com/recipes/japanese-okonomiyaki
and fill it will shredded cabbage and whatever else we have on hand, may or may not put any seafood or bacon in it, but typically shred any raw veg we use but will also julienne leftover roast veg, etc.
for sauce, we just use sriracha and mayo
