Vegetable tacos
Taco nights with friends and family are fun, even more so when the tacos are on the lighter side. This recipe uses a colorful mix of roasted and raw veggies. The roasted, crispy bits on the cauliflower and sweet potato add a heartiness that make you not miss the classic seasoned ground meat filling, even for a second. Experiment with different vegetables. I bet it will be great. Serve a salad on side and will feed four hungry humans.

Servings: 4

Prep time: 30 minutes


  • 1/2 large cauliflower head, cut into florets
  • 1 medium sweet potato, peeled, halved lengthwise, and sliced in 1/2 inch pieces
  • 1 pint cherry tomatoes, stemmed
  • 3 tablespoons extra-virgin olive oil
  • 1/2 red onion, thinly sliced and soaked in red wine vinegar for 20 to 30 minutes
  • 1 summer squash, thinly sliced
  • 2 ears of corn, shucked, sliced off of cob
  • 1/3 cup low-fat sour cream
  • 1 lime, juiced
  • 1 teaspoon ground cumin
  • 1/2 teaspoon ground chili powder
  • 1/2 cup chopped fresh cilantro, stems included
  • Coarse sea salt, to taste
  • Freshly ground black pepper
  • 8 to 12 all-natural or organic corn tortillas


  1. Preheat oven to 375 degrees.  
  2. Combine cauliflower, sweet potato, and tomatoes with olive oil, a four-finger pinch of salt, and a few grinds or a pinch of ground black pepper. 
  3. Toss together, place on a baking sheet, and roast until caramelized, about 25 to30 minutes. 
  4. Set roasted veggies aside in a bowl to cool. 
  5. Meanwhile, slice the red onion and start the vinegar soak for quick-pickled red onions. 
  6. Prepare the squash, corn, and remaining ingredients and combine everything together in a large bowl, including drained pickled red onions, and fold to incorporate. 
  7. Spoon into warm tortillas and serve.
