To start, sliced the bell peppers and the onion up. Thaw the shrimp if frozen. Preheat oven to 400℉.
Before starting the recipe a crucial step is to press the excess water out of the shrimp. Place the shrimp on a flat service and with a pepper towel gently press down removing the excess water from the shrimp. Be careful because pressing too hard will smash the shrimp. Gentle force only.
In a bowl toss the shrimp, bell pepper and onion in the provided fajita mix.
Then, place in oven and bake for 20 minutes. Serve with tortillas and Mexican sides like rice, guacamole or queso fundido.
