Mutton has a strong taste so it needs an awesome sauce to make delicious mutton burgers. A good and simple recipe comes from combining 3 of Leggo's pre-bottled sauces. Mix 1 teaspoon of each and spoon over mutton patties for a gourmand meal @home.
2) Bolognese chunky pasta sauce
3) Pesto with traditional basil
I used Prego pasta sauce as its already in my fridge.
