Preheat oven to 375 degrees F (200 degrees C). Grease muffin cups or line with muffin liners.
Combine flour, honey, salt and baking powder. Place oil (or butter) into a 1 cup measuring cup; add the egg and enough milk to fill the cup. Mix this with flour mixture. Fold in blueberries. Fill muffin cups right to the top.
Bake for 20 to 25 minutes in the preheated oven, or until done.
