Chicken Fajita Recipe

Get ready for game day! Lauren Grier from The Curious Plate is sharing this slow cooker chicken fajita subs recipe, featuring zesty queso made with Pepper and Onion Relish.

Are you getting excited?

I can hardly contain my excitement for game day!

Truth: my enthusiasm for one the of the world’s largest sporting events has nothing to do with the actual physical game of football. Don’t judge. I get more excited for the food and, of course, T.V. commercials. I love this time of year, because when else do you get a giant spread of your favorite comfort foods all at once?

I’m talking about little smokies, giant subs, dips, dips, and more dips. Oh, and you can’t forget about the wings! Simply put, there’s nothing better than football game snacks.

Anyway, my plan is to add these Slow Cooker Chicken Fajita Subs with Pepper Onion Relish Queso to our snack table. The secret ingredient that makes these subs an 11/10 situation is the Harry & David® Pepper and Onion Relish. A mixture of tomatoes, onions, bell peppers, vinegar, and jalapeños, this versatile relish adds a sweet yet subtle spice flavor to the chicken and queso. So, stuff your subs, pile on the queso, and watch these subs score a winning touchdown!
