Tried something new tonight. Turned out quite good.
I started with this base recipe: Kelsey's Cheesy Bacon Breasts.
I'm not fond of mustard, and one of the comments below the main recipe suggested marinading the chicken in vinegar, so I decided to start by taking the oil and a teaspoon of mustard powder and adding it to about a half cup of apple cider vinegar, then putting that and the chicken in a baggie and setting it in the fridge for an hour.
Once I was done marinading it, I discarded the marinade and put the chicken in a pan in the oven and cooked it for ten minutes, flipped it, and cooked for ten more, then put barbeque sauce and bacon bits (instead of real bacon) on it and cooked for five more minutes before adding the cheese, and finished with another five minutes.
Was absolutely delicious and very filling. I definitely recommend it. Would be great with some asparagus or broccoli.
