In a skillet heat the oil over medium heat.
Cook the onion and garlic, stirring, until the onion is limp, about 4 minutes.
Add the remaining ingredients and cook for 1 minute.
Reserve in the pan off heat.
Bring a large skillet or wide deep saucepan of water to a boil.
Add the broccoli and cook, uncovered, until crisp-tender and still bright green, 6 to 7 minutes.
Drain well and transfer to a serving platter or shallow bowl.
Spoon the onions on top.
