Ingredients

Instructions

  1. Step 1: In a small bowl, combine 1/4 cup apple cider vinegar, 1 teaspoon sugar, and 1/4 teaspoon salt. Add 1 small thinly sliced red onion and let sit at room temperature for at least 20 minutes to pickle.
  2. Step 2: Heat 2 tablespoons olive oil in a medium skillet over medium heat. Add 1 small diced yellow onion and 2 minced garlic cloves, sauté for 3-4 minutes until translucent and fragrant.

How do I store leftover Tomatillo and Black Bean Tacos with Pickled Red Onion?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep small, diced yellow onion from drying out.

Can I substitute ingredients in Tomatillo and Black Bean Tacos with Pickled Red Onion?

How do I scale Tomatillo and Black Bean Tacos with Pickled Red Onion for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
