Several years ago, I remember seeing a Philly Cheesesteak Casserole by Grassfed Mama. The idea intrigued me enough that it’s been stuck in my head all this time! Mine is quite a bit different from Angela’s in that it’s done completely in a skillet and has a sauce with it, but you should check hers out too in case it fits your taste buds better.
I would’ve loved to have included some fresh mushrooms in this skillet dish but didn’t have any on hand. 🙁 I know that green bell peppers are traditional with Philly Cheesesteaks, but even if I had some on hand, I wouldn’t have put them in. There are few foods in this world that I don’t enjoy, but green bell peppers are one of them. I sort of like them raw with Ranch dip, but cooked…no thanks. I can eat them, but I would not choose to do so. Onions on the other hand…bring ’em on!
I served this Philly Cheesesteak Skillet with Special Roasted Brussels Sprouts and green beans.
The Briana that pre-scheduled this post on February 1st asks you to pray for the Briana that is flying home from South Africa on the day this recipe is posted, February 27th. She knows that her future self can’t wait to get home and share all kinds of pictures and stories from her trip! Please give the future me some grace as I get back and reply to all the emails and comments that have been sent during my absence. <3

I'm sure this would be good with chicken as well!

I’m curious, do you like red, yellow, and orange peppers? I do not like green peppers but love the red, yellow and orange ones. People think I am nuts but the green ones are bitter and the others taste totally different than the green ones.
I am seeing this quite late so you are probably back already. I hope you had a great time. My daughter went on a mission trip to Africa when she was 17 and came back a changed person! She is 25 now and still talks about Africa.
Hi Lorenda! I just got back yesterday after a great trip! I actually do like red, orange, and yellow peppers – I completely agree with you that they have a much different taste!
Praying for you today!! (the philly cheesesteak looks great too!!)
Can’t wait to hear how your trip went! Blessings to you as you catch up again!
