In a greased skillet, sauté onions for one minute. Add shrimp and cook for one minute on one side at medium heat then flip on the other side and cook for 2 minutes at low heat. Remove from skillet and set aside.
In the same skillet, brown mushrooms. Add celery and bell pepper. Sprinkle with remaining cajun seasoning and sauté for 2 to 3 minutes.
Return shrimp on top and allow to heat up for 30 seconds without mixing.
Arrange lettuce on a platter. Spoon mushroom mixture onto each lettuce and top with shrimp. Drizzle with cajun dressing. Add some cherry tomatoes to make this shrimp lettuce wrap even more colorful. Enjoy!
