Oven Chicken Fajita Bake

Oven Chicken Fajita Bake

Colorful slices of bell peppers and red onions top off perfectly-seasoned chicken breast in this fajita-inspired chicken bake. Fajitas are typically made with strips of grilled meat, but this recipe adapts the concept a little to use whole chicken breasts instead. It’s just a slightly different way to try the same flavors.

Fajitas are typically served with tortillas; for a Paleo dinner ditch the corn and go with the Paleo cauliflower version instead. Alternately, you could substitute lettuce leaf wraps, or just enjoy the “good stuff” without the need for any wrapper at all.

Fajitas also play very nicely with plenty of condiments – some ideas for adding even more flavor:

If you’re trying to slowly ease a skeptic into Paleo with some familiar flavors, this would be a great recipe to start off with: everyone likes fajitas, so it’s familiar and comfortable even for complete beginners. It’s so good they might not even notice they’re technically eating “Paleo!”
