Make Ahead Tip: Cover and refrigerate the ketchup (Step 1) for up to 2 weeks.
To make your own fresh breadcrumbs, trim crusts from whole-wheat bread. Tear bread into pieces and process in a food processor until coarse crumbs form. To make fine breadcrumbs, process until very fine. To make dry breadcrumbs, spread coarse or fine breadcrumbs on a baking sheet and bake at 250°F until dry, about 10 to 15 minutes. One slice of bread makes about 1/2 cup fresh breadcrumbs or about 1/3 cup dry breadcrumbs. For store-bought coarse dry breadcrumbs we like Ian's brand, labeled “Panko breadcrumbs.” Find them at well-stocked supermarkets.
Oiling a grill rack before you grill foods helps ensure that the food won't stick. Oil a folded paper towel, hold it with tongs and rub it over the rack. (Do not use cooking spray on a hot grill.)
Broiler variation: Coat a broiler pan with cooking spray. Broil patties 3 to 4 inches from the heat source until an instant-read thermometer inserted into the center registers 160°F, 4 to 5 minutes per side.
