Bruschetta salad is a dish that should be eaten within 24-48 hours. It does have the tendency to get soggy if it sits longer than that. However, toasting the bread cubes does a great job to ensure that this salad doesn't end up too soggy. The bruschetta salad should sit for about 30 minutes after it's tossed with the dressing. It's best eaten within the same day it is made.
