Spinach Caprese Beef Tenderloin Salad

• Meanwhile, wash and dry produce. • Halve tomatoes. Dice mozzarella into 1⁄2-inch cubes. • Place tomatoes in a small bowl; toss with vinegar, 1 tsp sugar (2 tsp for 4 servings), and a big pinch of salt.

Pat chicken or beef dry with paper towels and season all over with salt and pepper. Heat a drizzle of oil in a large pan over medium-high heat. Cook chicken until browned and cooked through, 3-5 minutes per side, or cook beef to desired doneness, 4-7 minutes per side. Transfer to a cutting board.

• Halve ciabatta lengthwise; cut into 3⁄4-inch strips. Tear strips into rough cubes. Transfer to a large bowl; toss with 2 TBSP olive oil (4 TBSP for 4 servings), garlic powder, salt, and pepper. • Once chickpeas and onion have roasted 11 minutes, remove from oven and push to one side of sheet; carefully add croutons to empty side. (For 4, add croutons to a second sheet; toast on middle rack.) Return to top rack until golden and crispy, 7-9 minutes. Wipe out bowl. • Carefully transfer everything to bowl used to season croutons to cool.

• Remove tomatoes from bowl and set aside, leaving marinade behind. • Whisk half the mayonnaise and half the mustard into marinade until smooth. (For 4 servings, use all the mayonnaise and mustard.) • Slowly whisk in 4 TBSP olive oil (8 TBSP for 4), drizzling a little bit at a time, until creamy. Season with salt and pepper. Reserve 1 1⁄2 TBSP dressing (3 TBSP for 4) for serving.

• Add spinach to bowl with cooled chickpeas, onion, and croutons. Toss with remaining dressing until evenly coated.
