For Trim Healthy Mama this is an E recipe.To Store: Keep the leftover salad refrigerated, and it will last for 3-4 days. Keep it airtight, and you can add a little extra drizzle of lime juice to keep the avocados from browning. To Freeze: You can freeze the quinoa black bean salad for 1-2 months. I recommend leaving out the avocado just because the texture is better when it's not frozen—Thaw before eating.
