1 slice bread (I use "shokupan" - Japanese sandwich bread) or ½ cup panko (Japanese bread crumbs)
1 tablespoon milk
Salt and pepper
¼ cup okonomiyaki sauce (or tonkatsu sauce)
2 - 3 tablespoons ketchup
Instructions
In a medium bowl combine: onion, egg, ground turkey, bread crumbs, milk, salt and pepper. Using your hands, mix until well-incorporated.
Make patties about ¾ inch thick and 2 to 3 inches in diameter.
Heat olive oil on medium-high heat in a large pan with lid. Cook patties for about 5 minutes on each side. Pour a little water into the pan, just enough to cover the pan, and close with lid to steam the patty (about 2 minutes) until the water evaporates.
In a small bowl mix sauce ingredients: ketchup and okonomiyaki sauce or tonkatsu sauce. Or serve with ketchup, soy sauce or other condiment of choice on the side.
