Remove the spreadable butter from the refrigerator to soften. Place an oven rack in the center of the oven; preheat to 450°F. Wash and dry the fresh produce. Medium dice the baguettes. Halve the tomatoes. Halve, pit, and medium dice the nectarine. Pit and roughly chop the olives. In a large bowl, combine the halved tomatoes, diced nectarine, chopped olives, vinegar, and 1 tablespoon of olive oil. Season with salt and pepper. Set aside to marinate, stirring occasionally, at least 10 minutes. Taste, then season with salt and pepper if desired.

Line a sheet pan with foil. Transfer the diced baguettes to the foil. Drizzle with olive oil and season with salt and pepper. Toss to coat and arrange in an even layer. Toast in the oven 6 to 8 minutes, or until lightly browned. Leaving the oven on, remove from the oven. Reserving the sheet pan (and foil), transfer to the bowl of marinated tomatoes and nectarine.

towels; season on both sides with salt, pepper, and enough of the spice blend to coat (you may have extra). In a large pan, heat a drizzle of olive oil on medium-high until hot. Add the seasoned steak. Cook 4 to 5 minutes per side, or until lightly browned. Carefully transfer the browned steak to the sheet pan. Roast in the oven 5 to 8 minutes for medium-rare (125°F), or until browned and cooked to your desired degree of doneness.* Transfer to a cutting board; let rest at least 10 minutes.

*The USDA recommends a minimum safe cooking temperature of 145°F for steak. Cook the steak an additional 2 to 3 minutes to achieve this. Consuming raw or undercooked meat, poultry, fish, seafood or eggs may increase your risk of foodborne illness. 

While the steak rests, pick the mint leaves off the stems. To the bowl of panzanella, add the mayonnaise, arugula, and as much of the chile paste as you’d like, depending on how spicy you’d like the dish to be; toss to thoroughly coat. Taste, then season with salt and pepper if desired.

Find the lines of muscle (or grain) on the rested steak; thinly slice crosswise against the grain. Serve the sliced steak with the finished panzanella. Top the steak with the softened butter. Garnish the panzanella with the mint leaves (tearing just before adding). Enjoy!
