Preheat the oven to 180C/350F. Line a large baking tray with parchment paper.
In a large mixing bowl, combine your self-rising flour with Greek yogurt and mix until fully combined. Form the dough into a ball.
Lightly flour a wooden or kitchen surface. Add a tablespoon of flour onto the ball of dough. Transfer the ball of dough onto the floured surface. Press the ball down and divide into 8 pieces. Roll each piece of dough into a long, thin, sausage shape. Fold the corners over to form a pretzel shape. Place on the lined tray. Repeat the process, flouring the surface in between each one.
Brush the tops of each pretzel with either butter, milk, oil, or water. Sprinkle with coarse salt and bake for 20-22 minutes, or until golden. Allow pretzels to cool on the pan completely.
* Use either dairy-free butter, milk, oil or water. One of these MUST be used, or else the salt will not stick.
