Preheat oven to 400℉. Grease a muffin tin with butter or non-stick spray.
In your mixing bowl, whisk together the flour, sugar, salt and baking powder. Set aside.
Pour vegetable oil into a 1 cup measuring cup; add the egg and enough milk to fill the cup with 1 cup of liquid. Whisk the liquid together in the measuring cup, then add it to the mixing bowl. Whisk until just combined - batter should be slightly lumpy. Fold in strawberries with a spatula.
Pour batter into muffin tin. Bake approximately 12-14 minutes, or until a toothpick stuck in the middle of the muffin comes out clean. Let cool before removing from muffin pan.
In a small bowl, mix the powdered sugar and milk together until the lumps are gone. When the muffins are cool, drizzle the glaze over the top.
