Follow the steps in order for the best result.
Begin by steaming the broccoli florets until they are tender yet still retain a slight firmness. This should take approximately 4 to 6 minutes.
While the broccoli is steaming, finely mince the garlic cloves.
In a nonstick skillet, heat the olive oil over medium heat. Add the minced garlic and anchovies to the skillet and sauté for about one minute, until fragrant.
Incorporate the steamed broccoli into the skillet, stirring to ensure it is well combined with the garlic and anchovy mixture. Leave the broccoli in the skillet just long enough to heat through completely.
Serve immediately, sprinkled generously with freshly grated Parmesan cheese and a pinch of red pepper flakes for a touch of heat.
