Tender strips of pork tenderloin marinated in a zesty lime and chili blend, quickly seared with colorful bell peppers and onions for a vibrant, flavorful fajita filling.
In a bowl, whisk together olive oil, lime juice, garlic, cumin, chili powder, smoked paprika, salt, and pepper. Add pork strips, toss to coat, and let marinate for 10 minutes.
Heat a large skillet or cast-iron pan over high heat. Add pork strips in a single layer (work in batches if needed) and cook without stirring for 2 minutes, then flip and cook another 2 minutes until browned and cooked through. Transfer to a plate.
Reduce heat to medium-high. Add bell peppers and onion to the same skillet; cook, stirring occasionally, for 4-5 minutes until tender-crisp and lightly charred.
Return pork to the skillet, toss with vegetables, and cook for 1 minute to reheat.
Serve immediately with warm tortillas and desired toppings.
Tips
For extra flavor, add a pinch of cayenne pepper to the marinade.
Leftover fajita filling can be stored in an airtight container in the refrigerator for up to 3 days.
Warm tortillas by wrapping in foil and heating in a 350°F oven for 5 minutes, or microwave between damp paper towels for 30 seconds.
