Instructions

  1. Step 1: In a small bowl, combine 1/4 cup white vinegar, 1/4 cup water, 1 tbsp sugar, and 1/2 tsp salt. Stir until sugar dissolves, then add 1 small thinly sliced red onion. Let sit for 15 minutes to pickle.
  2. Step 2: Heat 1 1/2 cups refried beans in a small saucepan over medium heat until warmed through, about 5 minutes. Stir occasionally to prevent sticking.
  3. Step 3: Lightly brush 8 corn tostadas with 1 tbsp olive oil and toast in a 375°F oven for 5 minutes until crisp and warm.
  4. Step 4: Spread about 3 tbsp warm refried beans evenly over each tostada. Top with sliced avocado from 1 large ripe avocado, a spoonful of pickled red onions, and sprinkle with 1/2 cup crumbled cotija cheese and 1/4 cup chopped fresh cilantro.
  5. Step 5: Serve immediately with lime wedges for squeezing over each tostada.
