For the spice rub, heat a fry pan over a medium heat.
Add the red onion, garlic and ginger and cook for about 5 minutes or until the onion is transparent but not brown.
Add the remaining ingredients (except for oil and salt and pepper) and toss for 2 minutes or until spices have toasted.
Allow the mixture to cool. Once the mixture is cool add the olive oil and salt and pepper and mix to spice rub is well combined.
Add about half the rub to the lamb cutlets and allow to marinate for about 30 minutes.
Heat a pan to medium then cook the lamb cutlets in batches about 3-4 minutes each side.
Alternatively, cook on a bbq for 3-4 minutes each side or longer if you prefer your lamb well done.
