Recipe(tried): Chicken Fajitas

I made chicken fajitas tonight, with this wonderful marinade, and they were really good!

Chicken Fajita Marinade

Juice of 2 lemons
Juice of 1 orange
1 yellow onion, sliced
2 cloves garlic, minced
1-2 tsp. salt
1 tsp. chili powder
1 Tbsp. dry red pepper flakes
1/2 cup olive oil
2 tsp. oregano
2 tsp. ground black pepper
1 tsp. ground cumin

Combine all marinade ingredients; whisk until emulsified. Marinate chicken for at least 2-3 hours, overnight is better. Grill chicken about 8-10 minutes per side. Let chicken rest about 5 minutes, slice. Serve with warm tortillas, shredded cheese, sour cream, and guacamole, as desired.
