    total time: 1 hour

  • 8 corn tortillas
  • 3 tablespoons olive oil, divided
  • 1 1/2 pounds sweet potatoes, peeled, cut into 1 1/2-inch pieces
  • Salt and pepper
  • 1 teaspoon chili powder
  • 1 can (15.5 ounces) black beans, rinsed and drained
  • 1 clove garlic, peeled and finely chopped
  • 1/2 small red onion, minced
  • 1 avocado, halved, pitted, peeled, thinly sliced
  • 1 lime, cut into wedges
  • Cilantro leaves and pickled jalapenos, for serving


  1. Step 1

    Preheat oven to 450 degrees with racks in middle and bottom positions. On a rimmed baking sheet, lightly brush corn tortillas on both sides with 2 teaspoons olive oil. Bake on middle rack until golden and crisp, flipping halfway through, 10 to 12 minutes. On a separate rimmed baking sheet, toss sweet potatoes with 2 tablespoons oil. Season with salt and pepper and sprinkle with chili powder. Roast on bottom rack until tender and golden, flipping halfway through, about 30 minutes.

  2. Step 2

    Meanwhile, in a small saucepot, heat remaining teaspoon of oil over medium. Add garlic and cook until fragrant, about 1 minute. Add beans and 1/2 cup water, bring to a simmer and cook until liquid is reduced by half, about 3 minutes. Remove from heat and lightly mash beans with a fork. Spread beans on tostadas, top with sweet potato, jalapenos, onion, and avocado. Serve with lime wedges.

    Delicious and simple! Great flavors abound in this recipe. The only addition I added was a minced jalapeno sauteed with the garlic for the bean mixture. Served with cubed avocado, lime juice, fat free Greek yogurt and hot sauce. Yum!

    Delicious recipe. All week the vegetarian recipes have been wonderful. This one was really quick and easy to make. I added a layer of arugula on top. Everybody loved them.
