FAQ
Can I make this ahead?
Prep ingredients and dressing separately up to 4 hours ahead. Cook couscous and assemble within 30 minutes of serving to prevent the couscous from becoming soggy and avocado from browning.
Can I freeze this salad?
Not recommended. Couscous becomes mushy when thawed, avocado discolors, and fresh herbs lose texture. Store covered in refrigerator for up to 2 days instead.
What if I don't have fresh lime?
Bottled lime juice works in a pinch using 1 tablespoon. Zest is harder to replace but optional. Lemon can substitute for lime though it changes flavor profile.
