1 tablespoon chopped fresh parsley
2 tablespoons balsamic vinegar
2 teaspoons bottled minced garlic
1 teaspoon extravirgin olive oil
1 (16-ounce) can cannellini beans, rinsed and drained
3/4 teaspoon salt, divided
3/4 teaspoon cracked black pepper, divided
4 (4-ounce) beef tenderloin steaks, trimmed (1 inch thick)
