Step 1

Preheat oven to 425 degrees Fahrenheit. Line one large, rimmed baking sheet with parchment paper for easier cleanup.

Step 2

To roast the squash: On your prepared baking sheet, toss the cubed butternut in enough olive oil to lightly coat all sides, about 2 tablespoons. Sprinkle with 1 teaspoon chili pepper and a pinch of salt and pepper. Arrange the butternut in a single layer. Bake until the butternut is tender throughout and caramelized on the edges, about 30 to 35 minutes, tossing halfway.

Step 3

Meanwhile, to assemble the slaw: In a medium mixing bowl, combine the cabbage, black beans, green onion, cilantro, lime juice, olive oil and salt. Toss to combine, then taste and add additional lime juice and/or salt if necessary. Set aside to marinate.

Step 4

To prepare the guacamole: In a small bowl, combine the diced avocado, lime juice, coriander and salt. Mash with a pastry cutter, potato masher or fork until the mixture is blended and no longer chunky. Taste and add additional salt if necessary.

Step 5

To warm the tortillas: In a small skillet over medium heat, warm each tortilla on both sides before transferring to a plate and covering with a lint-free towel to keep warm. Repeat with each tortilla, stacking each warmed tortilla on the last.

Step 6

To assemble the tacos, spoon an ample amount of slaw down the center of your taco, top with roasted butternut and spread a spoonful of guacamole down the side. Top with garnishes of your choice and serve immediately.
