Fry your beef mince, onion and pepper in a skillet until browned. Break up with the back of a spoon. Season with garlic, taco seasoning and salt. Remove from the heat and place in a large bowl to cool slightly. Add your cream cheese and cheddar. Set aside.
Using a pizza cutter, slice your pizza base into slim triangles- you need 12-16 slices. On a seperate, lined baking tray arrange your triangles in a circle facing outwards ensuring they are slightly overlapping. It should look like a sun.
Place down your beef mix around the overlapping area of the dough ring. Brush the edges of the triangles (pointy end) with egg wash then fold over each triangle and tuck it underneath your inside circle. You should have a neat ring.
