Ingredients

  • Pickled Red Onions: 1 medium red onion (thinly sliced), 1/2 cup apple cider vinegar, 1/2 cup water, 1 tablespoon sugar, 1 teaspoon salt
  • Crispy Avocado Crema: 2 ripe avocados, 1/3 cup sour cream or Greek yogurt, 2 tablespoons lime juice (about 1 lime), 1/2 teaspoon salt, 1/4 teaspoon ground cumin, 1/2 cup panko breadcrumbs, 2 tablespoons olive oil
  • Tacos: 8 small corn or flour tortillas, 1 cup shredded lettuce, 1/2 cup crumbled cotija or feta cheese, 1/4 cup chopped fresh cilantro, 1 jalapeño (thinly sliced, optional), lime wedges (for serving)

Instructions

Prepare the Pickled Red Onions:
In a small bowl, combine apple cider vinegar, water, sugar, and salt. Add the sliced red onion, toss to coat, and let sit at room temperature for at least 5 minutes (or up to 1 hour for deeper flavor), stirring occasionally.
Make the Avocado Crema:
In a bowl, mash avocados until mostly smooth. Stir in sour cream (or Greek yogurt), lime juice, salt, and cumin until creamy.
Crisp the Avocado Crema:
Heat olive oil in a nonstick skillet over medium heat. Add panko and toast for 2–3 minutes, stirring constantly, until golden brown. Remove from heat and let cool. Gently fold the toasted panko into the avocado crema for a crispy texture.
Warm the Tortillas:
Heat tortillas in a dry skillet or wrap in foil and warm in the oven until pliable.
Assemble the Tacos:
Spread crispy avocado crema onto each tortilla. Top with shredded lettuce, a generous spoonful of pickled onions (drained), cotija or feta cheese, cilantro, and jalapeño slices if desired. Serve with lime wedges.
