Croutons:

4 slices sourdough, cut into 1/2-inch cubes
1/4 cup olive oil
1 teaspoon paprika
1/2 teaspoon coarse
kosher salt
Salad:
1-pound 90/10 ground beef
1 tablespoon
Worcestershire sauce
1 teaspoon onion powder
10 ounces chopped
romaine lettuce
1/2 cup shredded cheddar
8 cornichons, chopped
Salt and pepper to taste
Dressing:
1/4 cup mayonnaise
1/4 cup ketchup
2 tablespoons Dijon mustard
2 tablespoons
red wine vinegar
1 tablespoon pickle brine
Salt and pepper to taste
Heat oven to 400 F. Line a baking sheet with parchment.
Make croutons: In a mixing bowl, toss together bread cubes and oil. Season with paprika and salt. Bake until golden and crisp, about 15 minutes. Set aside.
Make salad: In a large skillet over medium heat, add beef. Sprinkle with onion powder and soy sauce. Season with salt and pepper. Cook beef, breaking it up with a spatula, until browned and cooked through, about 8 minutes. Use a slotted spoon to transfer beef to a salad bowl, leaving any fat behind. Let cool slightly, then add lettuce, cheese and cornichons.
Make dressing: In a mixing bowl, whisk together all ingredients. Season with salt and pepper.
Drizzle salad with dressing and toss to coat. Add croutons and toss again. Serve immediately.
