Instructions

  1. 1

    Preheat oven to 425°F (220°C) and position a rack near the top. Line a large sheet pan with foil.

  2. 2

    In a small bowl, mix 1.5 tsp chili powder, 1 tsp ground cumin, 1 tsp smoked paprika, 1/2 tsp garlic powder, 1/2 tsp onion powder, 1 tsp kosher salt, and 1/2 tsp freshly ground black pepper to make the fajita seasoning.

  3. 3

    On the sheet pan, toss 2 seeded, sliced red bell pepper, 2 seeded, sliced green bell pepper, and 1 large sliced yellow onion with half the 3 tbsp olive oil and half the seasoning mixture.

  4. 4
