Ingredients

1/2 c. plus 1 tbsp. extra-virgin olive oil

1/4 c. lime juice, from about 3 limes 

2 tsp. cumin

1/2 tsp. crushed red pepper flakes

1 lb. boneless skinless chicken breasts

Kosher salt

Freshly ground black pepper

2 bell peppers, thinly sliced

1 large onion, thinly sliced

Tortillas, for serving

Preparation

Step 1In a large bowl, whisk together 1⁄2 cup oil, lime juice, cumin, and red pepper flakes. Season chicken with salt and pepper, then add to bowl and toss to coat. Let marinate in the fridge at least 30 minutes and up to 2 hours. Step 2When ready to cook, heat remaining tablespoon oil in a large skillet over medium heat. Add chicken and cook until golden and cooked through, 8 minutes per side. Let rest 10 minutes, then slice into strips. Step 3Add bell peppers and onion to skillet and cook until soft, 5 minutes. Add chicken and toss until combined. Serve with tortillas.

Can I make any substituions? While we have standalone recipes for steak and shrimp there are a bunch of things you can sub into this one! If you like things spicy, subbing some or all of the bell peppers for something like poblanos or even jalapeños would be awesome. Want to add some zest to your dish? Sub the cumin for some homemade taco seasoning! What should I serve with fajitas? These can make up a meal all on their own, but we never turn down a good side dish. Go classic with some Mexican rice and refried beans. You can always serve up some chips with fresh salsa and an easy guacamole too!  What are the best fajita toppings? This is where you get to pile on all of your favorites! Classic fajitas might have sour cream, guacamole, and shredded cheddar. Why stop there? Top them with some corn salsa or a chimichurri! Those will really make your fajitas stand out.  Tried these yet?
