Preheat your oven to 350°F (175°C). Grease a loaf pan.
In a mixing bowl, combine flour, sugar, baking powder, and salt.
Stir in the chopped pistachios.
In another bowl, mix vegetable oil, milk, beaten eggs, and vanilla extract.
Combine wet and dry ingredients until just mixed.
Pour the batter into the prepared loaf pan.
Bake for 50 minutes or until a toothpick inserted into the center comes out clean.
Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
