For a few years now I have been a member of a program that offers taste tests at Jack in the Box. Membership is free!
Join the Jack in the Box Taste Test panel. They conduct research and taste tests in San Diego. I have been paid $35-$40 for about an hour of my time.

They send emails out to their members to qualify. They generally want a mix of ages and preferences that frequently eat fast food.
If you join and they ask please enter Matthew Henrickson as your referral!
