Ingredients:

1 lb lean beef mince,
salt,
pepper,
1 teaspoon cayenne pepper,
1 teaspoon garlic salt.

Filling one:
4 ounces mature cheddar cheese, grated.
finely chopped up onions.

Filling two:
4 ounces blue cheese,
2 ounces of finely chopped walnuts.

Filling three:
4 ounces monterey jack cheese,
2 ounces of finely chopped jalapeno peppers.

Directions:

Mix the top five ingredients together in one bowl.  Mix the last two ingredients together in another bowl. Form them into four balls. Put a deep well into each of the four balls of meat, and place a ball of grated cheese and chopped onion into that well.
Carefully cover the cheese and onion with the meat, place ball into BurgerMate and form into a patty.  Then put them in the freezer for approximately 1 hour before you cook them (this ensures they do not fall apart when you cook them).  Then cook them on the barbeque or in the frying pan.
