Yes, you can make any pasta salad in advance, but there are some limitations to how far in advance to make it. If you decide to make this southwestern pasta salad recipe in advance, I recommend preparing it no more than 24 hours ahead of time. The veggies simply won't hold up longer than that. If you refrigerate this vegan pasta salad, I recommend letting it sit for about an hour at room temperature before serving so the oil in the vinaigrette loosens up. When making this black bean pasta salad in advance, I recommend adding the avocado just before serving. It's a very delicate vegetable and may get overly mushy and brown if it sits.

It's also advisable to keep the items separate until you are ready to assemble the salad and serve.
