How to Make It
Bring wine, peppercorns, fennel seeds, and bay leaf to a boil in a saucepan; cook 10 minutes or until reduced by half. Place in a bowl; cool. Add 1 steak, turning to coat. Cover and chill 3 1/2 hours. Let stand at room temperature 30 minutes before grilling.
Combine tomatoes, 1 tablespoon oil, vinegar, 1/4 teaspoon salt, and 1/4 teaspoon pepper in a bowl; let stand 30 minutes.
Preheat grill to high.
Remove steak from marinade; discard marinade. Sprinkle marinated steak with 1/2 teaspoon salt and 1/2 teaspoon pepper. Cut remaining unmarinated steak in half. Combine 1/4 teaspoon salt, 1/4 teaspoon pepper, chile powder, and onion powder; rub over half of unmarinated steak (for Texas Barbecue Hash). Sprinkle remaining half of unmarinated steak with 1/4 teaspoon salt and 1/4 teaspoon pepper (for California Steak Salad). Coat grill grates with cooking spray. Add steaks to grill; grill 10 to 12 minutes, turning occasionally. Let marinated steak stand 10 minutes; cut across the grain into thin slices. Reserve remaining steak for California Steak Salad and Texas Barbecue Hash.
Coat squashes with cooking spray; sprinkle with 1/4 teaspoon pepper. Grill 3 to 4 minutes on each side.
Place remaining 3 tablespoons oil, 1/4 teaspoon salt, basil, and next 4 ingredients (through garlic) in a blender; blend until smooth. Divide squash and steak among 4 plates; top with tomato mixture, pesto, and panko.
Don't worry about the recipe's long total time, most of it is spent allowing the steak to marinate and come to room temperature before grilling.
