This steak salad recipe is tasty and easy to make. Flat-iron steak is quite tender; cook this lean cut of steak to medium-rare for the best flavor.

2 teaspoons finely chopped fresh sage

1 teaspoon salt

1 teaspoon freshly ground pepper

3 tablespoons extra-virgin olive oil

3 tablespoons red-wine vinegar

1 tablespoon Dijon mustard

3 anchovy fillets or 1½ teaspoons anchovy past

1 clove garlic

½ teaspoon freshly ground pepper

¼ cup extra-virgin olive oil

1 tablespoon minced garlic

½ cup crumbled blue cheese

12 cups frisée or curly endive, torn into pieces

4 flat-iron steaks ( ¾ inch thick, about 1½ pounds total), trimmed, or 1 flank steak, cut crosswise into 4 equal pieces

To marinate steaks: Combine 3 tablespoons oil, minced garlic, thyme, sage, salt and 1 teaspoon pepper in a gallon-size sealable plastic bag. Add steaks and turn the bag several times to coat them. Let the steaks marinate for 1 hour at room temperature or refrigerate for up to 1 day. 

To prepare dressing: Place vinegar, mustard, anchovy, garlic clove and ½ teaspoon pepper in a mini food processor (or blender) and process until smooth, scraping down the sides with a rubber spatula as needed. Add ¼ cup oil and process until creamy. Set aside for up to 1 hour or refrigerate for up to 1 day.

To cook steaks: Heat a ridged grill pan over medium-high heat until hot or preheat a grill to medium-high.

1.    Remove the steaks from the marinade. (Discard marinade.) Grill the steaks (two at a time, if using a grill pan) until browned on both sides and an instant-read thermometer inserted into the center registers 125 degrees to 130°F for medium-rare, 2 to 4 minutes per side. Transfer to a clean cutting board. 
2. To finish the salad: Toss frisee (or endive) with the dressing in a large bowl. Divide among 6 plates. Slice the steak diagonally across the grain into ¼-inch-thick slices. Top the salads with the steak and sprinkle with blue cheese
