This recipe started with a lot of leftover bread. I didn’t know what to do with it; it was stale, so I ground it into coarse breadcrumbs in the food processor. Okay, so now I have breadcrumbs, I thought. What to do? This was great fodder for, let’s see, meatballs? Frying batter? Savory stuffing? Nothing that sounded too appealing during these hot weeks of July.
