Ingredients

Scale
  • 1 lb boneless, skinless chicken breasts or thighs, sliced thinly
  • OR 1 lb flank steak or skirt steak, thinly sliced against the grain
  • 1 large red bell pepper, sliced
  • 1 large green bell pepper, sliced
  • 1 large yellow or orange bell pepper, sliced
  • 1 medium red onion, sliced
  • 2 tsp chili powder
  • 1 tsp smoked paprika
  • 1 tsp ground cumin
  • ½ tsp garlic powder
  • ½ tsp onion powder
  • ½ tsp dried oregano
  • Salt and freshly ground black pepper, to taste
  • 1 tbsp olive oil or avocado oil
  • Optional: 1-2 fresh jalapeños, sliced
  • Optional: Juice of 1 lime
  • Optional: Fresh cilantro, chopped

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice chicken breasts or steak thinly against the grain into strips about ¼ inch thick.
  3. Slice bell peppers and onion into strips about ½ inch thick.
  4. In a large bowl, combine chili powder, smoked paprika, cumin, garlic powder, onion powder, oregano, salt, and pepper. Add olive oil and stir to create a paste-like mixture.
  5. Add the sliced meat and veggies to the bowl and toss until everything is well coated in the seasoning mixture.
  6. Spread the meat and veggies out in a single layer on a prepared rimmed baking sheet.
  7. Bake in the preheated oven for 20-25 minutes, flipping and stirring halfway through (around 12 minutes) for even cooking.
  8. Check that meat is cooked through and veggies are tender with some charred edges.
  9. If using, squeeze fresh lime juice over the top and sprinkle chopped cilantro before serving.
  10. Serve warm with tortillas, guacamole, salsa, and sour cream or dairy-free alternatives.

Notes

Slice protein and vegetables evenly to ensure even cooking. Avoid overcrowding the pan to prevent steaming. Flip halfway through baking for caramelization. Let meat rest a few minutes after baking to keep it juicy. Adjust seasoning to taste. For gluten-free, use corn tortillas and check chili powder ingredients. For dairy-free, serve with avocado or salsa instead of sour cream or cheese.
