This bright, spicy sauce comes together quickly and can be made ahead for easy assembly—just wait until you’re ready to use it to add the mint. Try it with this Spicy Merguez Scramble or spoon it over roasted vegetables or eggs for a quick meal.
Stir together yogurt, lemon zest and juice, garlic, harissa, salt, and pepper in a small bowl until combined. Refrigerate, covered, up to 2 days. Stir in mint just before serving.
