My grill was out of commission, so I had to resort to cooking this via broiling (steak) & stovetop sauteeing (veggies). The result was a lovely sandwich & a nice, change-of-pace dinner for my family! Although we were divided between 4 & 5 stars, I ultimately decided to give this a 5... I am confident grilling would have brought out even more flavor to an already delicious dish! Used Grey Poupon Country Dijon and served on bolillo rolls (next time would toast sliced rolls) and add even more veggies as I found them real tasty. Thank you!!
