Step 1

Heat the olive oil in a medium skillet over medium heat. Saute the onions until translucent and tender, 3 to 4 minutes. Add the seafood seasoning and garlic and saute 1 minute longer. Let cool completely.

Step 2

In a large bowl, combine the crab meat, mayonnaise, parsley, mustard, salt, pepper, bread, egg, lemon zest and sauteed onions. Scoop the crab mixture using a 1/3-cup measure and form cakes (they may be slightly loose; see Cook's Note). Transfer to a baking sheet and refrigerate for 30 minutes.

Step 3

In a large skillet, heat 1 tablespoon olive oil over medium-high heat. Cook the crab cakes in batches, adding more oil if needed, until golden brown, about 3 minutes per side. Serve atop salad greens with a drizzle of Remoulade Sauce.

Step 4

Whisk together the mayonnaise, ketchup, capers, relish, mustard and lemon juice in a medium bowl until well combined. Season with salt and pepper.
