Sack Lunch: Beef and Mango Wraps and Black Bean Relish Recipe

Sack Lunch: Beef and Mango Wraps and Black Bean Relish Recipe

Despite the fact that roast beef sandwiches were probably born in the days when people frequently had large leftover roasts to use up, today we’re so accustomed to the deli counter that cooking your own sandwich meat might strike you as rather pretentious. I know I was surprised to discover how easy it is. Throwing a roast in the oven is much less time-consuming than, say, baking all your own bread (although that would be nice, too, wouldn't it?). It also saves money and tastes extra good—papery-thin deli meat has nothing on this.

Here is a wrap sandwich made with leftover roast beef. To make a dinner of the roast beef, chop some bell peppers, onions, and potatoes, toss them with olive oil, and add them to the sheet pan with the roast. To make meat for only a few sandwiches, just buy a smaller roast and monitor cooking closely. If roasting meat in June is not your idea of a good time, you could, of course, also make the wrap with deli meat. The black bean relish is a super fast side for this or any meal.

  • Yield:4, with leftover meat


  • 2 1/2 pounds eye-of-round (or other) beef roast
  • 2 tablespoons olive oil
  • Coarse salt
  • Pepper
  • 3/4 teaspoon dried thyme (optional)
  • 1 tablespoon Dijon mustard
  • 3 tablespoons fresh lime juice (from two limes)
  • 1/2 medium red onion, thinly sliced
  • 1 red bell pepper, seeded, halved lengthwise, and cut crosswise into thin strips
  • 1 mango (about 1 pounds, peeled and cut into 1/2-inch-wide strips
  • 4 whole wheat tortillas (10-inch) or wrapper of your choice
  • 4 cups loose spinach (about 5 ounces), trimmed, well washed, and dried
  • 1/2 medium red onion, finely chopped
  • 1 15-ounce can black beans, drained and rinsed
  • 1 cup chopped fresh cilantro
  • 2 tablespoons fresh lime juice
  • 1 tablespoon olive oil
  • Salt
  • Pepper
  • Cumin (optional)
  • Minced garlic (optional)


  1. 1.

    Preheat the oven to 400°F. Put the roast on a small sheet pan or baking dish, rub with 1 tablespoon olive oil, 1 1/2 teaspoons salt, 1/2 teaspoon pepper, and thyme (if using). When the oven is hot, roast 40-50 minutes, until the meat is tender and an instant-read thermometer inserted into its thickest part registers 130°F (for medium rare). Let meat cool. Store in an airtight container.

  2. 2.

    When you’re ready to make the wraps, slice the roast beef as thin as you like. Whisk together the mustard, lime juice, and remaining tablespoon olive oil; season with salt and pepper. Toss the onion, bell pepper, and mango with this dressing and set aside.

  3. 3.

    Line each tortilla with spinach, leaving a 1-inch border all around. Arrange beef slices down the center of each wrap and top the beef with the mango-vegetable mixture. Drizzle any extra dressing over the wraps.

  4. 4.

    Fold in the opposite sides of each wrap and roll up tightly.

    Toss all ingredients together in a bowl. I like this with a big dash of cumin and with minced garlic instead of onion.
