Step 1
Preheat the oven to 425 degrees. Toss the peppers and onions with half of the olive oil and half of the fajita seasoning. Place in a single layer on a large baking sheet.
Step 2
Bake for 7-10 minutes, until the peppers and onions are just beginning to soften. If you like crunchier veggies, take the peppers and onions out after 5 minutes.
Step 4
Carefully remove the baking sheet from the oven. Push the peppers and onions to one side and add the salmon to the baking sheet. Bake for 10-12 minutes or until your salmon is cooked to your liking. Serve in warm tortillas with fresh cilantro and extra lime juice. Add all your favorite toppings or pile on to greens or cauliflower rice.
