600g sirloin steak, cut into slices about a cm thick (you can ask your butcher to do this)
50g peanuts (salted is fine, but then don’t add any extra salt to the mixture)
1 teaspoon chilli powder
1 teaspoon paprika
1/2 teaspoon ground ginger
1/2 teaspoon garlic powder
1 teaspoon onion powder
Grind up the peanuts in a spice grinder or blender. Stop before they become peanut butter. Add the ground peanuts to all the other spices and mix well. Then put in a bowl with the steak slices smother it all over.
Grill over the direct heat on a BBQ, leaving the inside slightly pink. Serve with any left over peanut marinade if you like, and a tomato and onion salad.
