Fajita Marinade

  • ¼ cup olive oil as the flavorful base of the marinade
  • ¼ cup fresh lime juice squeezed from 2 limes for brightness
  • 2 tablespoons low sodium soy sauce to add savory depth
  • 1 tablespoon Worcestershire sauce for richness and umami
  • 1 teaspoon brown sugar to balance the acidity with a hint of sweetness
  • 1 teaspoon ground cumin for warm earthy flavor
  • 4 cloves garlic minced for bold, aromatic depth
  • 1 small jalapeño or ½ of a large one finely chopped with ribs and seeds removed
  • ½ teaspoon salt to season the mixture
  • ½ teaspoon black pepper for a mild kick
  • teaspoon crushed red pepper flakes optional - adjust for your preferred spice level

Chicken Fajitas

  • pounds boneless skinless chicken breast, cut into ½-inch thick strips for quick, even cooking
  • 2 teaspoons olive oil to sauté the chicken and vegetables
  • 1 small red onion thinly sliced for a pop of color and mild sharpness
  • 1 red bell pepper thinly sliced for sweetness
  • 1 yellow bell pepper thinly sliced to add brightness and balance

For Serving - choose your favorite toppings

  • 12 small flour tortillas warmed and ready for serving
  • sliced avocado or guacamole optional for creaminess
  • pico de gallo or salsa optional for fresh, zesty flavor
  • chopped fresh cilantro optional for a bright herbal note
  • sour cream optional for cool, tangy contrast
  • lime wedges optional for squeezing over just before serving

Instructions
 

  • Combine all marinade ingredients in a large zip-top bag or shallow dish. Seal the bag or whisk to mix thoroughly.
  • Add the sliced chicken strips and toss to coat evenly with the marinade. Refrigerate for 30-60 minutes.
  • After marinating, heat 2 teaspoons of olive oil in a large skillet over medium-high heat. Remove the chicken from the marinade and add it to the skillet. Discard the used marinade.
  • Cook the chicken for about 4 minutes, flipping once the underside is browned. It won't be fully cooked yet.
  • Add the sliced bell peppers and onions to the skillet. Continue cooking for 5-8 more minutes, stirring occasionally, until the chicken is cooked through and the vegetables are tender.
  • Warm the tortillas and serve with the chicken, peppers, and onions. Add your favorite toppings and enjoy.
