In small bowl, mix together 1/4 cup water with garlic powder, onion powder and mustard powder.
Add the olive oil to a large skillet and heat it on medium high heat. Add broccoli and salt. Cook 2 to 3 minutes until starting to brown, stirring occasionally.
Reduce heat to medium, and add the water and spices. Cook an additional 4 to 5 minutes until fork tender, stirring occasionally. Taste and add additional salt and black pepper as necessary. Serve immediately.
