  • 4 chicken breasts
  • 2 tbsp olive oil
  • 2 tbsp fajita or taco seasoning
  • 1/2 each red, yellow and green pepper, very thinly sliced
  • 1 small red onion, very thinly sliced
  • 1/2 cup shredded cheese (I use the pre-shredded tex mex kind)
  • Cilantro (optional for garnish)
  • Salsa and sour cream (for serving)

Roasted sweet potatoes (optional side)

  • 1 tbsp olive oil
  • 3 sweet potatoes, cut into 1-inch pieces
  • 2 tsp chili powder
  • 2 tsp paprika
  • 2 tsp garlic powder
  • 1 tsp salt


  • Preheat oven to 450 F. Toss sweet potatoes in olive oil and spices in a medium-sized ovensafe dish. Roast in oven for 25-30 min until tender.
  • Preheat BBQ to med-high, or preheat oven to 450 F. Meanwhile, make horizontal cuts across each chicken breast (see video if you're unsure how!) Rub chicken with olive oil and taco seasoning. Add bell peppers and red onions to each cut, then put each breast on the grill or in the oven.
  • Cook chicken for 15 min. Remove and top with cheese, then grill or bake another 5 min until cheese is melted. Remove from heat and serve alongside sweet potatoes, topping with optional cilantro, salsa and sour cream. Enjoy!



Nutritional info includes a side of sweet potatoes.
Make your own fajita seasoning using spices you already have on hand.
Serve with homemade fries, steamed veggies or a side salad.
Store any leftovers in the fridge for up to 5 days. Reheat in the oven for 10-15 minutes at 450° Fahrenheit or in the microwave for 1-2 minutes.
You can freeze this stuffed chicken, but the bell peppers don’t defrost very well, so I suggest freezing the chicken before you stuff it.
