Fajita Vegetables

  • 1 Red Bell Pepper
  • 1 Green Bell Pepper or poblano
  • ½ Red Onion
  • 2 TBSP Oil of Preference
  • ¼ TSP Salt or Garlic Salt

Fajita Seasoning

  • 1 TSP Cumin
  • ½ TSP Chili Powder
  • 1 TSP Paprika
  • 1 TBSP Oregano

Optional For Serving

  • 4-6 Corn Tortillas


Prepare the Ingredients

  • Preheat the oven to 425ºF.
  • Chop the red bell pepper, red onion, and poblano/green bell pepper into thin slices.
  • Combine all fajita seasoning ingredients together in a bowl.

Make the Fajitas

  • Spread bell peppers and onion on an aluminum-lined baking sheet.
  • Drizzle the fajita vegetables with neutral oil. Add ⅔ of the fajita seasoning onto the vegetables. Add salt or garlic salt.
  • Toss the vegetables gently to make sure seasoning is evenly coated on all of the vegetables.
  • Place fajita vegetables into the oven for 10 minutes.
  • While vegetables are roasting, slice the halloumi into ¼-½ in” thick medallions.
  • Once vegetables have roasted for 10 minutes, mix and move to one side of the baking sheet.
  • Add the halloumi, flat side down, onto the baking sheet. Sprinkle with the remaining seasoning and rub into both sides of the halloumi.
  • Place back in the oven for 12-15-minutes, or until vegetables are tender and roasted, and the halloumi is crispy and lightly browned.
  • Remove from the oven and turn off.
  • Serve as is, over rice or with warm corn tortillas.
