Place a large skillet over medium heat and add 1 Tbsp oil.

Add broccoli florets and sauté 4-5 minutes, partially covered with lid, stirring or tossing several times until broccoli is bright green and crisp-tender then remove from pan.

Tip: If you prefer softer broccoli, add 2 Tbsp water before covering with the lid and it will steam cook the broccoli.

Increase heat to high heat and add 1 Tbsp oil.

Add beef in a single layer and sauté 2 minutes per side or just until cooked through.
