Slice the bell peppers and white onion into thin strips and place them in a mixing bowl.
Add 2 tablespoons of olive oil and 2 tablespoons of fajita seasoning to the mixing bowl and mix until the vegetables are evenly coated.
Transfer the seasoned vegetables to a baking sheet and place on the middle rack of the oven. Cook for 10 minutes.
