• 1/2 teaspoon salt
• 1/2 teaspoon freshly ground pepper
• 1 teaspoon butter, divided
• 1 teaspoon olive oil, divided
• 2 medium portobello mushroom caps, sliced (about 1 1/2 cups)

Preparation

1. Sprinkle steak evenly with salt and pepper.

Turn steak, and cook 3 more minutes (rare), 4 minutes (medium-rare), or 5 minutes (medium). Remove steak from pan, and set aside.
