Preheat oven to 400℉. Grease a 12-cup muffin tin with nonstick cooking spray or butter. Set aside.
In a large bowl, whisk together the flour, baking powder, baking soda, salt, garlic powder and onion powder. Set aside.
In a separate bowl, whisk together the milk, melted butter and eggs. Add the wet ingredients to the dry ingredients. Stir just until combined.
Add the sundried tomatoes, feta and fresh parsley (or basil). Stir just until incorporated.
Divide batter among muffin cups. Bake at 400℉ for 18 to 20 minutes or until a toothpick inserted into the center comes out with little to no crumbs.
Notes
Grease the muffin tin instead of using liners. The cheese tends to stick to the liners making it difficult to get the muffins out of the paper liner.Store in an airtight container at room temperature for up to 3 days.Freeze for up to 3 months. Defrost in the refrigerator before bringing to room temperature.
