In a large bowl, mix the flour, yeast, sugar, and salt.
Add warm water and oil, then mix to form a dough.
Knead the dough on a floured surface for 8 to 10 minutes until smooth and elastic.
Place the dough in a greased bowl, cover, and let it rise in a warm spot for 1 hour or until doubled in size.
Punch down the dough, divide it into 8 to 10 pieces, and shape into thick rolls or squares.
Cover and let them rise again for about 15 to 20 minutes.
Braai (grill) over medium coals for 10 to 15 minutes, turning regularly, until golden brown and cooked through.
Serve warm with butter, cheese, jam, or as a side to grilled meat.
