Preheat your oven to 375°F (190°C).
In a large mixing bowl, combine 3 cups of self-rising flour, 1 tablespoon of sugar, and 1 teaspoon of salt. Stir to mix evenly.
Make a well in the center of the dry ingredients and pour in 1 1/4 cups of warm water and 2 tablespoons of vegetable oil.
Stir the mixture with a wooden spoon or spatula until a soft dough forms.
Turn the dough out onto a lightly floured surface and knead gently for about 5 minutes until smooth and elastic. Add a little flour if the dough is too sticky.
Shape the dough into a loaf and place it into a greased 9×5 inch (23×13 cm) loaf pan.
Let the dough rest for 10 minutes to rise slightly while the oven heats.
Bake the bread in the preheated oven for 30 minutes or until the top is golden brown and a toothpick inserted into the center comes out clean.
Remove the bread from the oven and let it cool in the pan for 10 minutes.
Transfer the bread to a wire rack to cool completely before slicing.
