I used this one as a starting point:

But I kind of went my own way with it. I sauteed onions, the bell pepper and garlic till very golden in olive oil. Then I toasted the panko along with them because I wanted the flavored oil to be infused in the breadcrumbs. I left out the cilantro entirely. But otherwise I followed the basic technique and made sure to taste it for seasoning before I added the egg.
