Tips: Chunk light tuna, which comes from the smaller skipjack or yellowfin, has less mercury than canned white albacore tuna. FDA/EPA advice recommends no more than 6 ounces of albacore a week; up to 12 ounces canned light is considered safe.
To make fresh breadcrumbs, trim crusts from whole-wheat bread. Tear bread into pieces and process in a food processor until coarse crumbs form. One slice of bread makes about 1/2 cup fresh crumbs. For dry breadcrumbs, spread the fresh crumbs on a baking sheet and bake at 250°F until crispy, about 15 minutes. One slice of fresh bread makes about 1/3 cup dry crumbs. Or use prepared coarse dry breadcrumbs. We like Ian’s brand labeled “Panko breadcrumbs.” Find them in the natural-foods section of large supermarkets.
