Chef Big DA high-performance lunch that bridges the gap between a Roman trattoria and a Texas post-oak pit. Thinly sliced flank steak is seared with spicy 'nduja and tucked into crusty ciabatta with a bright salsa verde.
In a small bowl, whisk together the chopped parsley, lemon zest, lemon juice, minced capers, and olive oil to create the salsa verde. Set aside to let the flavors emulsify.
The acidity in the lemon will mellow the saltiness of the capers over time.
Season the sliced flank steak generously with kosher salt and cracked black pepper. Ensure the meat is at room temperature for an even sear.
Heat a heavy cast-iron skillet over high heat until it begins to wisps of smoke appear. Add a touch of high-smoke-point oil if necessary.
Add the flank steak in a single layer. Sear undisturbed for 2 minutes to develop a deep bark, then toss.
Don't overcrowd the pan or the meat will steam instead of searing.
Reduce heat to medium-high and add the 'nduja and minced garlic to the skillet. Use a wooden spoon to break up the 'nduja so it melts and coats every fiber of the beef in spicy, rendered fat.
Remove the skillet from the heat. Place the split ciabatta rolls cut-side down in the pan for 30 seconds to soak up the residual spicy fat and juices.
Assemble the sandwiches by piling the 'nduja-coated beef onto the toasted rolls and drizzling generously with the bright salsa verde. Serve immediately.
The key here is the 'nduja—it’s a spreadable, spicy pork salume from Calabria that acts as a built-in sauce when it hits the heat of the pan. Make sure your pan is screaming hot before the steak hits; we want a crust that looks like mahogany. If you can't find 'nduja, a mix of double-concentrated tomato paste, smoked paprika, and plenty of red chili flakes will get you in the ballpark, but it won't have that same funky, fermented soul. serving this with a crisp arugula salad cuts the richness perfectly.
