1 avocado, sliced

½ small red onion, thinly sliced

HORSERADISH DRESSING:

½ cup mayonnaise

3 tablespoons grated horseradish

1 tablespoon freshly squeezed lemon juice

1 garlic clove, minced

Kosher salt and freshly ground black pepper to taste

DIRECTIONS

To prepare the croutons: Heat the oven to 400 degrees and line a baking sheet with parchment paper.

In a medium bowl, whisk the egg white with the olive oil, salt, oregano, garlic powder and pepper. Break the matzo into small pieces, about ½ inch, and add them to the bowl. Gently toss the mixture with a spoon until the matzo is fully coated, then spread it out on the baking sheet. Bake for 10 to 15 minutes, until the matzo crisps up into clusters. Remove from the oven and set aside to cool completely.

To prepare the steak: Rub the London broil with the grapeseed oil and season liberally with salt and pepper. (I like to use a lot of pepper so that it’s pepper-crusted.) Grill over high heat or broil on a sheet pan with the oven rack in the highest position for 6 to 8 minutes per side, until the steak is charred on the outside and cooked to medium-rare. Transfer the steak to a cutting board and set aside to rest for 10 minutes. Thinly slice crosswise and against the grain.

To make the dressing: In a small bowl, whisk together the mayonnaise, horseradish, lemon juice, garlic, salt and pepper until creamy. If a thinner consistency is desired, add water to thin.

To make the salad: In a large bowl, combine the romaine, cucumbers, carrot, radishes, avocado and onion. Toss with the horseradish dressing. Top with the meat and the croutons and serve.
