How to Make It
Cook bacon in a large nonstick skillet over medium-high, stirring occasionally, until crisp, 5 to 6 minutes. Place bacon on a plate lined with paper towels to drain.
Whisk together buttermilk, yogurt, chives, salt, and pepper in a bowl or glass measuring cup.
Divide quinoa evenly among 4 bowls. Sprinkle bacon evenly over each serving; top each with 1/2 cup tomatoes and one-fourth sliced avocado. Drizzle with 2 1/2 tablespoons buttermilk-chive dressing.
