5 Fry patties
Heat a pan over a medium-high heat with a drizzle of oil. Once hot, add the patties and fry for 3 min on each side or until browned and cooked through. Once browned, top with the grated cheddar, cover with a lid and cook for 1 min further or until the cheese has melted. Once melted, sprinkle with the crispy onions.
