Nigel Barden lamb burgers with avocado and feta on Drivetime with Simon Mayo

Nigel Barden serves up lamb burgers with avocado and feta as two key ingredients of the dish on Drivetime with Simon Mayo.

Feta is a brined curd white-cheese made in Greece from sheep’s milk, or from a mixture of sheep and goat’s milk.

Avocados provide nearly 20 essential nutrients, including fiber, potassium, Vitamin E, B-vitamins and folic acid. They also act as a “nutrient booster” by enabling the body to absorb more fat-soluble nutrients.

The ingredients for the dish are: 500g New Zealand lamb mince, 2 tbsp tomato sauce, 2 tsp Worcestershire or any other brown sauce, 1 spring onion, thinly sliced, 12 mint leaves, shredded, 1 avocado, ¼ tsp finely grated lime zest, 2 tsp lime juice, 2 heaped tablespoons mayonnaise, 1 tsp mustard, 50g feta cheese, crumbled, 2 beefsteak tomatoes, thinly sliced, 1 tsp extra virgin olive oil, 4 burger buns, split open and 1 butter lettuce, leaves separated.
