I really liked the idea of a low carb philly, but these fell short. The instructions don't match the ingredients, and if I follow the instructions exactly it comes out bland. I used butter instead of olive oil, that helped a bit. I also used Monterey jack instead of cheddar cheese, because I have never seen cheddar on a philly.
Next time I will marinate the beef over night and throw it on some buttered rolls lol
