   Time: PT5M

2. Prep Fajita Vegetables

   Slice the brown/yellow onion into thin strips across the grain. Run the garlic cloves through a microplane to create a fine paste.

   Time: PT3M

3. Butterfly and Slice Chicken

   Place each chicken breast on a cutting board, slice horizontally to open like a book, then cut into thin, even strips. If strips are too long, halve them.

   Time: PT4M

4. Make Taco Seasoning Blend

   Combine 4 g onion powder, 4 g garlic powder, 4 g paprika, 4 g ground cumin, 2 g dried oregano, 0.5 g chili powder, and a big pinch of salt in a small bowl. Stir with a spoon until evenly mixed.

   Time: PT1M

6. Season the Chicken

   Transfer the chicken strips to a separate bowl, add the remaining taco seasoning and 2 tsp olive oil, then massage until every strip is evenly coated.

   Time: PT1M

7. Cook Onions and Garlic

   Heat 1 Tbsp olive oil in the skillet over medium‑high heat. Add the seasoned red onion and sauté for about 4 minutes, stirring frequently. Add the garlic paste and cook an additional 1 minute, keeping the mixture moving to avoid burning.

   Time: PT5M

   Temperature: medium‑high

8. Cook the Chicken and Combine

Add the seasoned chicken strips (cook in batches if needed) and sear for about 1 minute, then continue cooking, stirring, for a total of 5 minutes until fully cooked through. Return the sautéed onions to the pan, toss for 30 seconds just to re‑heat everything together, then remove from heat.

   Time: PT6M

   Temperature: medium‑high
