Burger in a bowl

Instructions

1. Spray a large, heavy-based non-stick frying pan with low-calorie cooking spray and put it over a high heat. Add the beef, onion and garlic and stir-fry for 7-8 minutes, or until the beef is cooked through and the onions have softened. Take the pan off the heat and drain any fat from the mixture. Season lightly.
2. While the beef is cooking, put all the sauce ingredients in a bowl with 4 tbsp water and whisk until well combined.
3. Mix together the lettuce, gherkins, onions and tomatoes and divide between 4 wide bowls. Spoon the beef mixture on top, divide the sauce between the burgers and serve hot.
