It really doesn't get more simple than this.
Take one French loaf. Cut it into thick part slices (about 3/4 of the way through). Combine 125g butter, a bunch of chopped garlic (the recipe says 2-3 cloves, but I put a LOT more than that in), a tablespoon of chopped parsley and some black pepper. Beat it till it's smooth. (I made it in advance, melting the butter, because it's COLD in Dunedin, and butter doesn't go soft. Then I left it to harden partially.)
Spread the butter mixture between each slice of bread. Wrap bread in foil and bake for 10-15 mins on 180C.
Basic garlic bread, ftw. Delicious. NOM.
