Ingredients:
1/4 cup balsamic vinegar
1 teaspoon Dijon mustard
1/4 teaspoon salt
1/4 teaspoon coarsely ground pepper
1/4 cup olive oil
2 tablespoons prepared horseradish
2 beef strip loin grilling steaks (8 oz/225 g each), halved crosswise
2 sweet red peppers quartered
1 Vidalia onion cut in 1/2-inch thick rings
Directions;
In small bowl, combine vinegar, mustard and half each of the salt and pepper; gradually drizzle in oil, whisking until emulsified. Stir in horseradish. Remove 2 tbsp and set aside for topping.
Season steaks with remaining salt and pepper. Place on greased grill over medium-high heat; close lid and grill, brushing often with horseradish mixture and turning once, until medium-rare, about 8 minutes. Remove from grill. Spoon reserved horseradish topping on steaks; let stand for 5 minutes.
Meanwhile, add red peppers and onion to grill; grill, covered, turning occasionally and brushing with horseradish mixture, until softened slightly, about 5 minutes. Serve with steak.
