To make the steaks: In a large bowl, combine the milk and bread crumbs; let stand for 10 minutes.
In a saute pan over medium heat, warm the olive oil; add in the onion; stir/saute about 5 minutes until soft and golden.
Add in the garlic; cook 1 minute, stirring occasionally; add in the curry and ginger; cook 1 minute, stirring occasionally.
Remove pan from heat and let cool to room temperature.
Add the cooled sauteed onion and the rest of the steak ingredients to the soaked bread crumbs; gently mix until well blended.
With wet hands, shape the meat into four patties of equal size and thickness (4 inches in diameter and 1 inch thick).
Place steaks on a platter, cover with plastic wrap and refrigerate 30 minutes before grilling.
Lightly brush or spray both sides of the steaks with olive oil and grill over direct medium heat 8-10 minutes, turning once halfway through grilling time.
After turning, glaze the top of each steak with 1 tablespoon ketchup and allow it to cook into the meat; serve hot.
