Ingredients

  • 2 medium yellow squash, cut into 1/2″ pieces (5 to 6 cups)
  • 2 medium zucchini, cut into 1/2″ pieces (5 to 6 cups)
  • 2 tablespoons extra-virgin olive oil
  • Kosher salt
  • 3 small shallots, very thinly sliced
  • 1 cup red wine vinegar
  • 2 tablespoons granulated sugar
  • 1/2 teaspoon za’atar
  • 1/4 cup tahini
  • 2 tablespoons chopped fresh parsley
  • 2 tablespoons fresh lime juice
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon granulated garlic
  • 8 (6″) corn tortillas
  • 1/2 cup homemade or store-bought hummus

Instructions

  1. Step 1: Preheat the oven to 450°F (232°C). On a baking sheet, toss the yellow squash and zucchini with olive oil and season generously with kosher salt. Roast the vegetables, stirring halfway through, until they are softened and beginning to caramelize, about 25 to 30 minutes.
  2. Step 2: While the vegetables roast, place the thinly sliced shallots in a small heatproof bowl. In a small saucepan over medium heat, combine the red wine vinegar, granulated sugar, za’atar, and a pinch of salt. Heat the mixture, stirring occasionally, just until it is hot and steaming, but do not let it simmer. Pour the hot vinegar mixture over the shallots and let them sit for 10 to 15 minutes to pickle.
  3. Step 3: In a medium bowl, whisk together the tahini, chopped parsley, lime juice, smoked paprika, granulated garlic, and salt to taste. Gradually whisk in 4 to 5 tablespoons of cold water until the sauce is thin and smooth.
  4. Step 4: During the last 5 minutes of roasting, arrange the corn tortillas on a separate sheet pan or wrap them in foil. Warm them in the oven until they are pliable and heated through.
  5. Step 5: To assemble the tacos, spread about 1 tablespoon of hummus in the center of each warm tortilla. Top with a generous spoonful of the roasted squash and zucchini, followed by some of the pickled shallots. Drizzle the tahini sauce over the top before serving.

Tips & Variations

  • Try adding a sprinkle of crumbled feta or cotija cheese for extra flavor and creaminess.
  • If za’atar is unavailable, substitute with a mix of thyme, sesame seeds, and sumac for a similar taste.
  • For a heartier meal, add some cooked black beans or grilled chicken to your tacos.
  • Use other seasonal vegetables like bell peppers or eggplant in place of squash for variation.

Storage

Store any leftover roasted vegetables and sauce separately in airtight containers in the refrigerator for up to 3 days. Warm the vegetables gently in the oven or microwave before assembling tacos. The tortillas are best consumed fresh but can be wrapped and kept for up to 2 days.

How to Serve

The image shows six small round toasted flatbreads placed on a white marbled surface, each topped with three layers. The bottom layer is a light brown creamy spread, followed by roasted yellow and green zucchini slices arranged in a slightly overlapping manner. On top, there are thin, curly strands of pale pink pickled onions scattered lightly over the vegetables. A smooth, orange creamy sauce is drizzled generously over each flatbread, with some drips visible on the surface around them. The flatbreads have a slightly charred texture, giving a toasted look with dark brown spots. The whole scene is bright and fresh, with balanced colors and textures. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make the pickled shallots in advance?

Yes, pickled shallots can be prepared a day ahead and refrigerated, which actually enhances their flavor.

What can I use instead of tahini in the sauce?

If you don’t have tahini, you can substitute with plain Greek yogurt or a nut butter like almond butter, though the flavor and texture will differ slightly.

Instructions

  1. Roast the Vegetables: Preheat your oven to 450°F. On a baking sheet, toss the yellow squash and zucchini pieces with olive oil and a generous pinch of kosher salt. Spread them out evenly. Roast in the oven for 25 to 30 minutes, stirring once halfway through, until the squash softens and begins to caramelize.

In a small saucepan over medium heat, combine red wine vinegar, sugar, za’atar, and a pinch of salt. Heat until the liquid is hot and steaming but not boiling, stirring occasionally. Pour the hot vinegar mixture over the shallots and let sit for 10 to 15 minutes to pickle and soften the shallots.

  5. Assemble the Tacos: Spread about 1 tablespoon of hummus in the center of each warm tortilla. Top with a generous scoop of roasted squash and zucchini, followed by some pickled shallots. Drizzle the tahini lime sauce over everything, and serve immediately.
