Place half the oil, garlic and zest in a large snap lock bag. Season, add lamb and toss to coat. Marinate for 5 minutes.
Meanwhile, place the mint, sugar and a good pinch of salt in a jug. Stir in 1/3 cup (80ml) boiling water and set aside to cool. Once cooled, stir in the vinegar. Taste and adjust the seasoning.
Heat a large non-stick frying pan over medium-high heat and cook cutlets for 2-3 minutes each side or until cooked to your liking. Set aside on a plate loosely covered with foil to rest for 3 minutes.
Drizzle coleslaw with remaining oil, season and toss to coat. Serve cutlets with mint sauce (or mint jelly), coleslaw, extra mint and lemon wedges.
Tips
Lamb loin chops, lamb leg or rump steaks or forequarter chops would also work well in this recipe.
Slice up any leftover meat from the cutlets to create a salad or wrap in Lebanese bread or pita pockets.
Mint jelly instead of sauce also works well with lamb cutlets.
