I only had steak and potatoes on hand and did not feel like driving to the store to pick up any more food. This came out so good! I found a few recipes online that used similar ingredients so that's how I came up with this. Hope you enjoy!
Season with salt, pepper, garlic, and onion to taste. I use about a pinch of everything.
Pour in balsamic vinagerette.
Stir everything together and then put into baking dish.
Use a baking dish that is large enough that the salad dressing covers the steak and potatoes completely. Otherwise the steak on top will come out hard and the potatoes will not be cooked all the way through.
