Preheat oven to 425 degrees. Lightly spray a 12-cup mini muffin pan with cooking spray.
In a medium bowl, stir together the flour, 1/2 cup oatmeal, baking powder, garlic powder, oregano, basil, salt.
In a small bowl whisk together the remaining ingredients. Pour into the flour mixture, stirring until just combined. Do not overmix or muffins may be tough. Spoon into min-muffin cups, filling them about 3/4 full.
Bake for 18-20 minutes, or until a wooden toothpick inserted in the center of the muffin comes out clean. Invert the pan onto cooling rack to remove muffins. Allow to cool.
Serve with leftover veggies to make mini sandwiches!
